We need to do this or all LPSS devices are left in reset state when resuming from D3 on some Baytrails. The devices with the fractional clock divider also have zeros for N and M values after resuming unless they are reset. Li Aubrey found the root cause for the issue. The idea of using power domain for LPSS came from Mika Westerberg.
