Subject: [PATCH v2 0/1] Enable SPCR table for console output on RISC-V

The ACPI SPCR code has been used to enable console output for ARM64 and
X86. The same code can be reused for RISC-V. Furthermore, SPCR table is
mandated for headless system as outlined in the RISC-V BRS
Specification, chapter 6.

Changes in v2:
- Added code to handle early_init_dt_scan_chosen_stdout().
