f1e9e2b062 [efi] Align EFI image sections by page size 
For optimal memory permission management, PE sections need to be
aligned by the platform's minimum page size.  Currently, the PE
section alignment is fixed to 32 bytes, which is below the typical 4kB
page size.  Align all sections to 4kB and adjust ELF to PE image
conversion accordingly.

1cc8756511 [efi] Discard .pci_devlist.* sections for EFI images 
As per https://github.com/ipxe/ipxe/pull/313#issuecomment-816018398,
these sections are not required for EFI execution.  Discard them to
avoid implementation-defined alignment malforming binaries.
