ath11k: read and write registers below unwindowed address
For QCA6390, host can read and write registers below unwindowed
address directly without programming the window register. For
registers below bar0 + 4k - 32, host can read and write regardless
of the power save state. Shadow registers are located below
bar0 + 4K - 32.
Before MHI power up, there is no need to wakeup MHI so ini_done is
added to indicate it.
Tested-on: QCA6390 hw2.0 PCI WLAN.HST.1.0.1-01740-QCAHSTSWPLZ_V2_TO_X86-1
