If clk_get_by_name() returns 0 it means it executed successfully while now
we consider it as an error. So let's check if return value is negative to
be an error. Otherwise this prevents "axi" and "disp_axi" to be enabled.

- DHSOM update:
   - Remove nWP GPIO hog
   - Increase SF bus frequency to 50Mhz and enable SFDP
   - Disable video output for DHSOM
   - Disable EFI
   - Enable DFU_MTD support
- Create include file for STM32 gpio driver private data
- Split board and SOC STM32MP15 configuration
- Device tree alignement with v5.15-rc6 for STM32MP15
- Add binman support for STM32MP15x
- Normalise newlines for stm32prog
- Update OTP shadow registers in SPL

The stm32 gpio driver private data are not needed in arch include files,
they are not used by code except for stm32 gpio and pincontrol drivers,
using the same IP; the defines for this IP is moved in a new file
"stm32_gpio_priv.h" in driver/gpio.

This patch avoids to have duplicated file gpio.h for each SOC
in MPU directory mach-stm32mp and in each MCU directory arch-stm32*
and allows to remove CONFIG_GPIO_EXTRA_HEADER for all STM32.

The current EFI video driver only works when running in the stub. In that
case the stub calls boot services (before jumping to U-Boot proper) and
copies the graphics info over to the efi table. This is necessary because
the stub exits boot services before jumping to U-Boot.

The app maintains access to boot services throughout its life, so does not
need to do this. Update the driver to support calling boot services
directly.

Enable video output for the app. Note that this uses the
EFI_GRAPHICS_OUTPUT_PROTOCOL protocol, even though it mentions vesa.

A sample qemu command-line for this case is:

   qemu-system-x86_64 -bios /usr/share/edk2.git/ovmf-ia32/OVMF-pure-efi.fd
   -drive id=disk,file=try.img,if=none,format=raw -nic none
   -device ahci,id=ahci -device ide-hd,drive=disk,bus=ahci.0

Two displays supported by the sunxi display driver (each one used by a
single board) require initialization over I2C. Both previously used
i2c_soft; replace this with the i2c-gpio instance that already exists in
those boards' device trees (sun5i-a13-utoo-p66 and sun6i-a31-colombus).

Since the i2c-gpio nodes are not referenced by any other node in the
device trees (the device trees have no panel node), the I2C bus is
selected by its node name.

This panel initialization code was the only i2c_soft user, so the
i2c_soft GPIO setup code can be removed now as well.

This clarifies which callers must be updated to complete the DM_GPIO
conversion.

The only remaining caller of name_to_gpio in generic code is inside the
!DM_GPIO block in cmd/gpio.c. DM_GPIO is always selected on sunxi, so
that code cannot be reached. And after this commit, there are only two
remaining implementations of name_to_gpio.

As part of migrating to DM_GPIO and DM_PINCTRL, eventually we will
remove the asm/arch/gpio.h header. In preparation, clean up the various
files that include it.

Some files did not contain any GPIO code at all, so this header was
completely unused.

A few files contained only legacy platform-specific GPIO code for
setting up pin muxes. They were left unchanged, as that code will be
completely removed by the DM_PINCTRL migration.

The remaining files contain some combination of DM_GPIO and legacy GPIO
code. For those, switch to including asm/gpio.h (if it wasn't included
already). Right now, this header provides both sets of functions,
because ARCH_SUNXI selects GPIO_EXTRA_HEADER. This will still be the
right header to include once the DM_GPIO migration is complete and
GPIO_EXTRA_HEADER is no longer needed.
