ACPICA: SPCR: Update the SPCR table to version 4 

ACPICA commit 1eeff52124a45d5cd887ba5687bbad0116e4d211

The Microsoft Serial Port Console Redirection (SPCR) specification
revision 1.09 comprises additional fields [1]. The newly added fields
are:
- RISC-V SBI
- Precise Baud Rate
- namespace_string_length
- namespace_string_offset
- namespace_string

Additionaly, this code will support up to SPCR revision 1.10, as it
includes only minor wording changes.
