ARM: debug-ll: Add support for r7s9210
Enable low-level debugging support for RZ/A2M (r7s9210).
The RZA2MEVB board uses either SCIF2 (SDRAM enabled) or SCIF4 (HyperRAM
only) for the serial console.
Note that "SCIFA" serial ports on RZ/A2 SoCs use a compressed register
layout, hence add support for that to renesas-scif.S.
