Benjamin Doron 39cf79900f util/inteltool: Actually read SATA init data from SIRD ...

Fix issue where registers always seem to contain their own offset.

After writing the desired register into SIRI, the requested data is
returned in SIRD. This register is 4 bytes after SIRI, commonly 0xA4.

Tested on TGL-H (SATA SIR registers are common), genuine data is
returned.
