9ef5ccaa71 efi_loader: fix SectionAlignment, FileAlignment
The alignment of sections in the EFI binaries generated by U-Boot is
incorrect.

According to the PE-COFF specification [1] the minimum value for
FileAlignment is 512. If the value of SectionAlignment is
less then the page size, it must equal FileAlignment.

Let's set both values to 512 for the ARM and RISC-V architectures.

dfbc2be47e riscv: revert Complete efi header for RV32/64
EDK II refuses to load the EFI binaries created by U-Boot.
The reason is an incorrect PE-COFF header. The number of
data directories does not match NumberOfRvaAndSizes.
This leads to a failed consistency check in
PeCoffLoaderGetPeHeader():

    SizeOfOptionalHeader - HeaderWithoutDataDir) !=
    NumberOfRvaAndSizes * sizeof(DATA_DIRECTORY))

17a50bd689 efi_loader: add Linux magic to RISC-V crt0
Add the Linux magic to the EFI file header to allow running our test
programs with GRUB's linux command.

MajorImageVersion = 1 indicates a kernel that can consume the
EFI_LOAD_FILE2_PROTOCOL. This allows to dump the GRUB provided intird with
our initrddump.efi tool.

84c3db2ea3 riscv: Fix efi header for RV32
RV32 should use PE32 format instead of PE32+ as the efi header format.
This requires following changes
1. A different header magic value
2. An additional parameter known as BaseOfData. Currently, it is set to
   zero in absence of any usage.

a35c33c0dc efi_loader: use predefined constants in crt0_*_efi.S
We should use predefined constants instead of magic numbers.

Move some constant definitions from include/pe.h to
include/asm-generic/pe.h.

Use these constants in crt0_*_efi.S.

a33a4efd27 riscv: efi: Generate Microsoft PE format compliant images
Per Microsoft PE Format documentation [1], PointerToSymbolTable and
NumberOfSymbols should be zero for an image in the COFF file header.
Currently the COFF file header is hardcoded on RISC-V and these two
members are not zero.

This updates the hardcoded structure to clear these two members, as
well as setting the flag IMAGE_FILE_LOCAL_SYMS_STRIPPED so that we
can generate compliant *.efi images.
