soc: sunxi: select CONFIG_PM

Selecting CONFIG_PM_GENERIC_DOMAINS without CONFIG_PM leads to a
build failure:

WARNING: unmet direct dependencies detected for PM_GENERIC_DOMAINS
  Depends on [n]: PM [=n]
  Selected by [y]:
  - SUN20I_PPU [=y] && (ARCH_SUNXI [=n] || COMPILE_TEST [=y])

Unfortunately platforms are inconsistent between using 'select PM'
and 'depends on PM' here. CONFIG_PM is a user-visible symbol, so
in principle we should be using 'depends on', but on the other hand
using 'select' here is more common among drivers/soc. Go with the
majority for now, as this has a smaller risk of introducing circular
dependencies. We may need to clean this up for consistency later.
