ArmPlatformPkg/HdLcd: add missing LcdIdentify()
Commit r18308 ("ArmPlatformPkg/LcdGraphicsOutputDxe: check PrimeCell ID
before initializing") introduced a LcdIdentify() function to the PL111
LCD driver that makes it fail gracefully when executed on hardware that
does not have the IP. However, the LcdGraphicsOutputDxe driver is shared
with the HdLcd driver, which now fails to build due to the fact that it
has no LcdIdentity() function. So add a dummy implementation that always
returns EFI_SUCCESS.
