[PATCH v5 11/11] drivers: PL011: add ACPI probing for SBSA UART

[Andre Przywara]

From: Graeme Gregory <graeme.gregory at linaro.org>

Add the necessary driver boilerplate to let the driver be used when
the respective ACPI table is discovered by the ACPI subsystem.

[Andre: change table name, add MODULE_DEVICE_TABLE entry and improve
	commit message]
