From: Pierre Gondois <pierre.gond...@arm.com> 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.
