For for case of lazyapply method, API fdt_fixup_board_enet() gets
invoked before DPL being deployed. This leads to an issue that
fsl-mc fdt fixup status marked as fail and dprc driver didn't get
registered in linux boot.
Fixes this issue by calling fdt_fixup_board_enet() for case when
DPL is deployed successfully in lazyapply method.

Commit 608b0c4ad4 ("serial: Use next serial device if probing fails")
added code to search for more serial devices if the default one was not
probed correctly.
Unfortunately, that breaks omap3_evm. So while investigating why that is
the case, let's disable the full search for everyone but bcm283x where it
is needed.

The variable cfi_flash_num_flash_banks is defined iff

unconditionally in the function cfi_flash_init_dm. This leads to a
undefined variable compile error when CONFIG_SYS_MAX_FLASH_BANKS_DETECT

Fix this by always defining the cfi_flash_num_flash_banks variable.

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.

v1 -> v2:
- Use efi_status_t in all occurences
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.
