ASoC: SOF: Intel: lnl: Correct rom_status_reg
[ Upstream commit b852574c671a9983dd51c81582c8c5085f3dc382 ]
ACE2 architecture changed the place where the ROM updates the status code
from the shared SRAM window (and HFFLGP1QW0 in ACE1) to HFDSC register for
the status and HFDEC (HFDSC + 4) for the error code.
The rom_status_reg is not used on LNL because it was wrongly assigned based
on older platform convention (SRAM window) and it was giving inconsistent
readings.
Add new header file for lnl specific register definitions.
