ath11k: add 64bit check before reading msi high addr

Browse source

In QCN9074 ath11k boot, firmware crash is observed in 64-bit
builds and is due to wrong 64 bit MSI address size. This patch
fixes the firmware crash. Read msi high addr if 64-bit addresses
allowed on MSI.

Tested-On: QCN9074 hw1.0 PCI WLAN.HK.2.4.0.1.r1-00026-QCAHKSWPL_SILICONZ-2
