As I mentioned in the 5/9 patch I'm concerned that the current
definition of PCIE_PWRSEQ and PCIE_PWRSEQ_QCA6390 will effectively hide
the fact that QCA6390 may need additional configuration since the menu
item will only show up if you have already enabled PCIE_PWRSEQ.
Yes I see that these are set in the defconfig in 9/9 but I'm concerned
about the more generic case.

I'm wondering if there should be a separate config QCA6390 within ath11k
which would then select PCIE_PWRSEQ and PCIE_PWRSEQ_QCA6390
