gpio: Enable hogging support in SPL

Use the CONFIG macros to conditionally build the GPIO hogging support in
either the SPL or U-Boot, or both, depending on the configuration. Also
call the GPIO hog probe function in the common SPL board initialization
as an equivalent to adding it to the U-Boot init sequence functions.

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.

microblaze: Convert generic platform to DM gpio

Converting GPIO to DM requires to do changes in reset subsystem
that's why support for Microblaze soft reset via sysreset and GPIO
sysreset support was added.
These two patches enables enabling GPIO DM.
Microblaze soft reset is bind at last reset method.

GPIO reset is handled via sysreset with adding this fragment to DT.

gpio-restart {
compatible = "gpio-restart";
gpios = <&reset_gpio 0 0 0>;
/* 3rd cell ACTIVE_HIGH = 0, ACTIVE_LOW = 1 */
};

hard-reset-gpio property is not documented and also handled.
Conversion is required.

Unfortunately do_reset is required for SPL that's why use only soft
microblaze reset for now.
