ath11k: use remoteproc only with AHB devices

QCA6390 and other PCI devices use MHI based firmware loading and do not use
remoteproc, so enable it only for AHB devices.

Tested-on: QCA6390 hw2.0 PCI WLAN.HST.1.0.1-01740-QCAHSTSWPLZ_V2_TO_X86-1
Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.1.0.1-01238-QCAHKSWPL_SILICONZ-2
