DynamicTablesPkg: Fix generated _HID value for SBSA
SSDT tables describing an SBSA compatible serial port receive an '_HID'
value of 'ARMH0011'. This value represents a PL011 serial port.
This patch:
- Generates an 'ARMHB000' instead
- References the 'ACPI for Arm Components 1.0 - 2020' document
specifying the '_HID' values to use.
