Series wifi: ath12k: Add new features to ACPI | expand

Commit Message

Lingbo Kong Jan. 13, 2025, 7:48 a.m. UTC 
Currently, the timing for accessing the ACPI table is inappropriate.

Due to special ACPI requirements, the ACPI table must be obtained before
downloading the board data file. Therefore, adjust the timing for accessing
the ACPI table accordingly.

This patch will not affect QCN9274, because only WCN7850 supports ACPI.

Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3
