arm64: efi: increase EFI PE/COFF header padding to 64 KB
Commit76085aff29
("efi/libstub/arm64: align PE/COFF sections to segment alignment") increased the PE/COFF section alignment to match the minimum segment alignment of the kernel image, which ensures that the kernel does not need to be moved around in memory by the EFI stub if it was built as relocatable. However, the first PE/COFF section starts at _stext, which is only 4 KB aligned, and so the section layout is inconsistent. Existing EFI loaders seem to care little about this, but it is better to clean this up. So let's pad the header to 64 KB to match the PE/COFF section alignment. Fixes:76085aff29
