Merge functionality duplicated in bx50v3 and mx53ppd: the logic
is the same except that process_vpd is called at different phases.
Also read_vpd could end up in error, so there is no VPD data in this
case - it shouldn't be processed.

board: ge: bx50v3: fix initialization of i2c bus0

I2C bus 0 was not initialized correctly. There is an offset between i2c
index and the structure number of pad info. So i2c bus 0 can be in an
inconsistent state.

This problem become visible on B{4,6}50v3 with the CPUC HW watchdog enabled.
Sometimes when the CPUC HW watchdog interrupted the boot process, U-Boot was
not able to read VPD from I2C/EEPROM and the system failed to boot up again,
because a device connected to that bus was stuck in data transfer state (from
previous boot attempt) and there was no method to recover (struct
mxc_i2c_bus::idle_bus_fn was not set) courtesy of incorrect initialization.

SPDX: Convert all of our single license tags to Linux Kernel style

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

Enable the hardware watchdog on bx50v3 to cause it to reset in the event
the board hangs.

Configure GPIO_9 pin as WDOG1_B so that a watchdog timeout results in a
full system reset.

The watchdog is used and reconfigured by systemd approximately 1.7 seconds
into boot. Adding a few seconds for U-Boot and a few more seconds as a
safety margin.

Note that the PCIe controller is _not_ put back into a safe state prior
to board reset. This is a problem if board reset is implemented as CPU
reset.

board: ge: bx50v3: program MAC address to I210

There are two I210s on the b850v3 and one on the b450v3 and b650v3.
One is connected to Marvell 88e6240 which is already programmed.

Follow the flow documented in doc/README.enetaddr: set the
enet[0-9]*addr environment variable and let the driver program the
hardware.

The mapping from the driver's index to the environment variable's name
is documented in README: Note for Redundant Ethernet Interfaces. It is
assumed that eth_devices for the controllers on the board are always
indexed in the same order.

The environment variables are removed after programming the hardware
because the variables seem to influence MAC addresses also after U-Boot.
Specifically the MAC address of FEC (MC interface) would be incorrectly
set: 'ethaddr', which maps to the first I210 chip and is set to I210's
default address read from the driver by eth_write_hwaddr in eth_legacy.c
because the variable is undefined (not set even by bx50v3.c), would
result in the eth0 interface's MAC address to be set to I210's default
address.

board: ge: bx50v3: move FEC MAC address programming to driver

Instead of programming the hardware directly in the board
implementation, follow the flow documented in doc/README.enetaddr: set
the enet[0-9]*addr environment variable and let the driver program the
hardware.

This avoids duplicating the implementation as it already exists in the
driver (drivers/net/fec_mxc.c: fec_set_hwaddr).

The mapping from the driver's index to the environment variable's name
is documented in README: Note for Redundant Ethernet Interfaces. It is
assumed that eth_devices for the controllers on the board are always
indexed in the same order, i.e. FEC always has the index 2.

The FEC driver does *not* set the flag Set MAC Address on Transmit (bit
set_eth0_mac_address used to do but this is unnecessary as the Linux
networking stack fills in the MAC address.

board: ge: Enable access to i2c bus 1 and 2

The change in i2c configuration added to support access to the VPD has
inadvertantly caused access to i2c buses 1 & 2 to be lost. This has
resulted in the configuration for the PMIC to be attempted on the wrong
bus and thus isn't taking effect.

Add the required configuration to return access to buses 1 & 2. In order
to ensure that any users of the bus numbering prior to addition in VPD
patches work, add buses before configuration related to mux on bus 0 and
tweak VPD bus usage to fit new numbering scheme.
