[edk2-devel] [PATCH 19/37] OvmfPkg: remove gEfiLegacyBiosGuid

["Laszlo Ersek" <lersek@redhat.com>]

At this point, gEfiLegacyBiosGuid is unused; remove it.

This shrinks the list of resources scheduled for removal to:

- GUIDs (protocols or otherwise):
  - gEfiLegacy8259ProtocolGuid
  - gEfiLegacyBiosPlatformProtocolGuid
  - gEfiLegacyBiosProtocolGuid
  - gEfiLegacyInterruptProtocolGuid

- headers:
  - FrameworkDxe.h
  - Protocol/Legacy8259.h
  - Protocol/LegacyBios.h
  - Protocol/LegacyBiosPlatform.h
  - Protocol/LegacyInterrupt.h

- PCDs:
  - PcdEbdaReservedMemorySize
  - PcdEndOpromShadowAddress
  - PcdHighPmmMemorySize
  - PcdLegacyBiosCacheLegacyRegion
  - PcdLowPmmMemorySize
  - PcdOpromReservedMemoryBase
  - PcdOpromReservedMemorySize
