In ath11k, bus_params were added with an intention to hold
parameters related to bus (AHB/PCI), but this is not true
as some bus parameters being different between chipsets of
the same bus.
With the addition of WCN6750 to ath11k, bus parameters are
going to be entirely different among AHB devices. Therefore,
it is wise to move bus_params to hw_params and get rid of
bus_params entirely.
Also, mhi_support parameter is not used anywhere in the driver,
remove it from bus_params.
Tested-on: WCN6750 hw1.0 AHB WLAN.MSL.1.0.1-00887-QCAMSLSWPLZ-1
