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.

ARM: tegra: Tegra114 pinmux cleanup

This renames all the pinmux pins, drive groups, and functions so they
have a prefix which matches the type name. These lists are also auto-
generated using scripts that were also used to generate the kernel
pinctrl drivers. This ensures that the lists are consistent between the
two.

The entries in tegra114_pingroups[] are all updated to remove the columns
which are no longer used.

All affected code is updated to match.

This introduces a few changes to pin/group/function naming and the set of
available functions for each pin. The new values now exactly match the
TRM; the chip documentation. I adjusted a few entries in
pinmux-config-dalmore.h due to this.

ARM: tegra: pinmux naming consistency fixes

Clean up the naming of pinmux-related objects:
* Refer to drive groups rather than pad groups to match the Linux kernel.
* Ensure all pinmux API types are prefixed with pmux_, values (defines)
are prefixed with PMUX_, and functions prefixed with pinmux_.
* Modify a few type names to make their content clearer.
* Minimal changes to SoC-specific .h/.c files are made so the code still
compiles. A separate per-SoC change will be made immediately following,
in order to keep individual patch size down.

Tegra114: Dalmore: Add pad config tables/code based on pinmux code

Pad config registers exist in APB_MISC_GP space, and control slew
rate, drive strengh, schmidt, high-speed, and low-power modes for
all of the pingroups in Tegra30. This builds off of the pinmux
way of constructing init tables to configure select pads (SDIOCFG,
for instance) during pinmux_init().

Currently, no padcfg entries exist. SDIO3CFG will be added when the
MMC driver is added as per the TRM to work with the SD-card slot on
Dalmore E1611.

Tegra114: Dalmore: Always use DEFAULT instead of DISABLE for lock bits

The pinmux code issues a warning if the caller attempts to disable the
lock bit in a pinmux register, since this is impossible (once it's
locked, the only way to unlock it is to reset the device/pmt controller).

The I2C/DDC/CEC/USB macros expect a lock setting to be passed in,
and the previous setting of DISABLE caused the pinmux table parsing
code to issue the warning. Changing the lock bits in these table
entries to DEFAULT (i.e. don't touch it) fixes this.

Use the latest tables & code from our internal U-Boot repo.
The SDMMC3_CD, CLK_LB_IN and CLK_LB_OUT offsets in the pingroup
table were off by a few indices, causing the pinmux init code to
write bad data to the PINMUX_AUX_ regs. This also enabled the lock
bit, which made it impossible to reconfig the pads correctly for
SDMMC3 (SD card on Dalmore) operation. Also fixes SPI_CS2_N,
USB_VBUS_EN0, HDMI_CEC and UART2_RXD/TXD muxes.
