x86: doc: Fix reference to EFI doc in U-Boot

Since commit f3b5056c4e ("efi_loader: split README.efi into two
separate documents"), the original README.efi was renamed to
README.u-boot_on_efi, but x86 doc still refers to the old one.

This updates the x86 doc to reference both README.u-boot_on_efi and
README.uefi.

EFI Support
-----------
U-Boot supports booting as a 32-bit or 64-bit EFI payload, e.g. with UEFI.
This is enabled with CONFIG_EFI_STUB. U-Boot can also run as an EFI
application, with CONFIG_EFI_APP. The CONFIG_EFI_LOADER option, where U-Booot
provides an EFI environment to the kernel (i.e. replaces UEFI completely but
provides the same EFI run-time services) is not currently supported on x86.
This is enabled with CONFIG_EFI_STUB to boot from both 32-bit and 64-bit
UEFI BIOS. U-Boot can also run as an EFI application, with CONFIG_EFI_APP.
The CONFIG_EFI_LOADER option, where U-Booot provides an EFI environment to
the kernel (i.e. replaces UEFI completely but provides the same EFI run-time
services) is not currently supported on x86.

See README.efi for details of EFI support in U-Boot.
See README.u-boot_on_efi and README.uefi for details of EFI support in U-Boot.

64-bit Support
--------------
U-Boot supports booting a 64-bit kernel directly and is able to change to
64-bit mode to do so. It also supports (with CONFIG_EFI_STUB) booting from
both 32-bit and 64-bit UEFI. However, U-Boot itself is currently always built
64-bit mode to do so. However, U-Boot itself is currently always built
in 32-bit mode. Some access to the full memory range is provided with
arch_phys_memset().
