The ArmBootArch field of the FADT table is 16-bit wide. The
VS2017 compiler reports 'warning C4244: '=': conversion from
'UINT32' to 'UINT16', possible loss of data' when assigning the
CM_ARM_BOOT_ARCH_INFO.BootArchFlags value as the width of this
field in CM_ARM_BOOT_ARCH_INFO is 32-bit wide.
To fix this warning, update the CM_ARM_BOOT_ARCH_INFO struct
to make the BootArchFlags field 16-bit wide. This also makes
it compatible with the ACPI FADT specification.
