[edk2-devel] [edk2-platforms][PATCH v5 2/9] Platform/Sgi: Update the datatype of PcdSmmuBase from u32 to u64

["Prabin CA" <prabin.ca@arm.com>]

From: Vivek Gautam <vivek.gautam@arm.com>

On RD-N2 and previous generation platforms, the base address was within
32-bit region. However, on upcoming platforms, the SMMUv3 base address
is beyond 32-bit address region. So, update the datatype of SMMUv3 base
PCD.
