ArmPlatformPkg/NorFlashDxe: correct NumOfLba vararg type in EraseBlocks()
According to the PI spec, Volume 3,
EFI_FIRMWARE_VOLUME_BLOCK2_PROTOCOL.EraseBlocks():
> The variable argument list is a list of tuples. Each tuple describes a
> range of LBAs to erase and consists of the following:
> * An EFI_LBA that indicates the starting LBA
> * A UINTN that indicates the number of blocks to erase
(NB, in edk2, EFI_FIRMWARE_VOLUME_BLOCK_PROTOCOL is a typedef to
EFI_FIRMWARE_VOLUME_BLOCK2_PROTOCOL.)
In this driver, the NumOfLba local variable is defined with type UINTN,
but the TYPE argument passed to VA_ARG() is UINT32. Fix the mismatch.
In addition, update the DEBUG macro invocation where NumOfLba is formatted
with the %d conversion specifier: UINTN values should be converted to
UINT64 and printed with %Lu or %Lx for portability between 32-bit and
64-bit.
