mips: mscc_sgpio: Add the MSCC serial GPIO device (SIO)

This add support for the the MSCC serial GPIO driver in MSCC
VCoreIII-based SOCs.

By using a serial interface, the SIO controller significantly extends
the number of available GPIOs with a minimum number of additional pins
on the device. The primary purpose of the SIO controller is to connect
control signals from SFP modules and to act as an LED controller.

This adds the base driver.

gpio: mscc-bitbang-spi: Add a simple gpio driver for bitbgang spi

The VCore III SoCs such as the Luton but also the Ocelot can remap an SPI
flash directly in memory. However, for writing in the flash the
communication has to be done by software.

Each of the signal used for the SPI are exposed in a single register. In
order to be able to use the soft-spi driver, the management of this pin
is done through this simple gpio driver.

Even if the main purpose of this driver is to be used by soft-spi, it can
still be used as a normal gpio driver but with limitation: for example
the first pin can't be used as output.

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.
