RealTimeClockLib instances are consumed by edk2's
EmbeddedPkg/RealTimeClockRuntimeDxe driver. In its entry point function
InitializeRealTimeClock(), the driver:
(1) calls LibRtcInitialize(),
(2) sets the GetTime(), SetTime(), GetWakeupTime() and SetWakeupTime()
runtime services to its own similarly-named functions -- where those
functions wrap the corresponding RealTimeClockLib APIs,
(3) installs EFI_REAL_TIME_CLOCK_ARCH_PROTOCOL with a NULL protocol
interface.
Steps (2) and (3) conform to PI v1.8 sections II-9.7.2.4 through
II-9.7.2.7.
However, this means that LibRtcInitialize() (of any RealTimeClockLib
instance) should not itself (a) set the GetTime(), SetTime(),
GetWakeupTime() and SetWakeupTime() runtime services, nor (b) install
EFI_REAL_TIME_CLOCK_ARCH_PROTOCOL. The runtime service pointers will be
overwritten in step (2) anyway, and step (3) will uselessly install a
second (NULL-interface) EFI_REAL_TIME_CLOCK_ARCH_PROTOCOL instance in the
protocol database. (The protocol only serves to notify the DXE Foundation
about said runtime services being available.)
Clean up ArmPlatformPkg/PL031RealTimeClockLib accordingly (it only has
code that's redundant for step (3); it does not try to set "gRT" fields).
(Note that the lib instance INF file already does not list
gEfiRealTimeClockArchProtocolGuid.)

[lersek@redhat.com: shorten patch subject line]
The RealTimeClockLib class header in edk2 mistakenly declares a function
called LibRtcVirtualNotifyEvent(). No component ever calls this function
crossing module boundaries; all RealTimeClockLib instances in edk2 and
edk2-platforms are supposed to register (and do register) their
SetVirtualAddressMap() notification functions.
Rename LibRtcVirtualNotifyEvent() to VirtualNotifyEvent(), and make it
static, in preparation for removing the LibRtcVirtualNotifyEvent()
declaration from the lib class header later.
Build- and boot-tested with ArmVirtQemu.

Current HDLCD and PL111 platform libraries do not support display modes

historical confusion, they do not support the UEFI default
PixelBlueGreenRedReserved8BitPerColor format
In LcdPlatformLib for PL111, LcdPlatformQueryMode returns the pixel
format as PixelRedGreenBlueReserved8BitPerColor which is wrong, because
that does not match the display controller's pixel format which is set
to BGR in PL111Lcd LcdHwLib.
Also it is not possible to configure pixel format as RGB/BGR for the
display modes for a platform at build time.
This change adds PcdGopPixelFormat to configure pixel format as
PixelRedGreenBlueReserved8BitPerColor or
PixelBlueGreenRedReserved8BitPerColor or
PixelBitMask.
With this change, pixel format can be selected in the platform specific
.dsc file for all supported display modes.
Support for PixelBitMask is not implemented in PL111 or HDLCD LcdHwLib
libraries, hence HDLCD and PL111 platform libraries will return error
EFI_UNSUPPORTED if PcdGopPixelFormat is set to PixelBitMask. Indeed,
it is not clear what selecting PixelBitMask might mean, but the option
is allowed as it might suit a custom platform.
