ath10k: Don't call SCM interface for statically mapped msa region
For some targets ex: QCS404, SCM permissions for MSA region is
statically configured in TrustZone fw. Add SCM call disable option
for such targets to avoid duplicate permissions.
Testing: Tested on WCN3990 HW
Tested FW: WLAN.HL.3.1-01040-QCAHLSWMTPLZ-1
