stable inclusion from stable-v6.6.33 commit 8aeb3dc8b3cd4a485d19dd2d719d47a7f4ed4e7f category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IAD6H2

--------------------------------
[ Upstream commit 1f1b820dc3c65b6883da3130ba3b8624dcbf87db ]
ACE1 architecture changed the place where the ROM updates the status code from the shared SRAM window to HFFLGP1QW0 register for the status and HFFLGP1QW0 + 4 for the error code.
The rom_status_reg is not used on MTL because it was wrongly assigned based on older platform convention (SRAM window) and it was giving inconsistent readings.
