c6fa5df6aa efi_loader: Always use EFIAPI instead of asmlinkage
EFI calls are usually defined as asmlinkage. That means we pass all parameters
to functions via the stack x86_32.

On x86_64 however, we need to also stick to the MS ABI calling conventions,
which the EFIAPI define conveniently handles for us. Most EFI functions were
also marked with EFIAPI, except for the entry call.

So this patch adjusts all entry calls to use EFIAPI instead of the manual
asmlinkage attribute.

While at it, we also change the prototype of the entry point to return
efi_status_t instead of ulong, as this is the correct prototype definition.

6698bb343f efi: Conflict efi_loader with different stub bitness
We have 2 users of the EFI headers: efi_loader and the EFI stub. Efi_loader
always expects that the bitness of the definitions it uses is identical to
the execution.

The EFI stub however allows to run x86_64 U-Boot on 32bit EFI and the other
way around, so it allows for different bitness of EFI definitions and U-Boot
environment.

This patch explicitly requests via Kconfig that efi_loader can only be enabled
if the bitness is identical. Because we can run efi_loader on x86_64 without
EFI stub enabled, it also ensures that this case propagates the correct ABI
constraints.

This patch introduces a new pinctrl driver that can actually properly mux

owner of the gpio device. The previous GPIO driver gets moved into a
subdevice of the pinctrl driver, bound to the same OF node.

automatically from the pinctrl driver and GPIO support is still available

libfdt_env.h is supposed to provide system-dependent defines.

scripts/dtc/libfdt/libfdt_env.h from upstream DTC is suitable

For compiling U-Boot, we need to override such system-dependent

<libfdt.h> selects a proper one.  Maybe, we should split header
inclusion completely, but I do not want too many patches at one.
