The VS2017 compiler reports 'warning C4244: '=': conversion from 'const UINT32' to 'UINT8', possible loss of data' when the ACPI table revision field is being updated. The width of the revision field in the EFI_ACPI_DESCRIPTION_HEADER struct is 8-bit wide. Therefore, to fix the above warning make the ACPI Table revision field usage 8-bit wide across Dynamic Tables Framework.
