misc: amd-sbi: Add support for Turin platform
- RMI registers addresses in AMD new platforms are 2 bytes,
on previous processors the address size is 1 byte.
- Implement logic to identify register address size at runtime.
- The identification is done in first transaction using the
Revision register.
- The revision register can be read using 1 byte in both, older and
newer platforms.
- However, sending 1 byte on later platform can cause unrecoverable error.
