ARM: vexpress: Add Cortex-R Series UART, selectable via DEBUG_LL
The Cortex-R series processors on Versatile Express have a different memory map to the RS1 and CA9X4 tiles. Most of the platform difference can be expressed in device-trees, but the UART definitions for LL_DEBUG cannot. This patch defines the UART location for R-Series processors on versatile-express, allowing low-level debug and output from the decompressor. These definitions are selectable via Kconfig Signed-off-by: Jonathan Austin <jonathan.austin@arm.com> CC: Pawel Moll <pawel.moll@arm.com>
