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.

distro bootcmd: Allow board defined UBI partition and volume names

This commit allows overriding the default assumption that the boot UBI
MTD partition is named 'UBI' and the UBI volume is 'boot'. A board
desiring to use a legacy or alternative NAND layout can now define the
following two extra environment variables:

bootubipart=<some_ubi_partition_name>
bootubivol=<some_ubi_volume_name>

EXAMPLE:

[include/configs/some_board.h]
---8<-------------------------------------------------------------------
[...]
#include <config_distro_defaults.h>

#define MEM_LAYOUT_ENV_SETTINGS \
DEFAULT_LINUX_BOOT_ENV

#define BOOT_TARGET_DEVICES(func) \
func(UBIFS, ubifs, 0)

#include <config_distro_bootcmd.h>
[...]
#define CONFIG_EXTRA_ENV_SETTINGS \

"bootubivol=rootfs\0" \
