The SDM845 QHP PHY doesn't have designated RX region. Corresponding RX
table is empty, so we can drop it completely.

All PCIe PHYs on sc8180x platform have 2 lanes, so change the number of
lanes to 2.

This is not really a bug (and this is just a cleanup) so you can drop
the fixes tag (which looks incorrect anyway).

This is not the right fixes tag either. This should have been 

Fixes: f839f14e24f2 ("phy: qcom-qmp: Add sc8180x PCIe support")

Should this also be backported (i.e. should you add a stable tag)?

Maybe, but it's not that important. We don't have corresponding DT
bits, so it seems not that urgent.
