Some code cleanup for the EFI stub, to drop obsolete code, and to switch
to newer and more ergonomic APIs for managing pool allocations and EFI
handle buffers.

No functional changes intended, except for the UGA removal.

Ard Biesheuvel (7):
  x86/efistub: Drop long obsolete UGA support
  efi/libstub: Use C99-style for loop to traverse handle buffer
  efi/libstub: Simplify GOP handling code
  efi/libstub: Refactor and cleanup GOP resolution picker code
  efi/libstub: Simplify PCI I/O handle buffer traversal
  efi/libstub: Use cleanup helpers for freeing copies of the memory map
  efi/libstub: Use __free() helper for pool deallocations
