imx: imx8ulp: upower: replace magic number with macro

Browse Source 
The swton indicates the logic switch, magic number 0xfff80 is hard
to understand, so use macro.

Some board design may not have MIPI_CSI voltage input connected per
data sheet. In that case, the upower power on API may dead loop mu to wait
response, however there is no response. So remove MIPI_CSI here, let
linux power domain driver to runtime enable the power domain.
