[U-Boot] [PATCH v2 2/6] x86: efi: payload: Generate Microsoft PE format compliant image

[Bin Meng]

Per Microsoft PE Format documentation [1], PointerToSymbolTable and
NumberOfSymbols should be zero for an image in the COFF file header.
Currently U-Boot is generating u-boot-payload.efi image in which
these two members are not zero.

This updates the build rules to tell linker to remove the symbol
table completely so that we can generate compliant *.efi images.
