Log: Add an APB base/size for the QCA955X for an upcoming QCA955x specific APB mux. It's larger than the AR71xx because it needs to replace the nexus for some devices (notably wifi) and the wifi driver (if_ath_ahb.c) reads the SPI data directly at early boot whilst it's memory mapped in. I'm eventually going to rip it out and replace it with a firmware interface similar to what exists for the if_ath_pci.c path - something early on (likely something new that I'll write) will suck in the calibration data into a firmware API blob and that'll be accessed from if_ath_ahb.c. But, one thing at a time.
