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.
