[PATCH v2 1/2] pxamci: remove the ifdef CONFIG_REGULATOR

Don't wrap regulator_get() inside an ifdef CONFIG_REGULATOR anymore, as
now it degenerates and returns NULL when the regulator framework is
disabled (since commit be1a50d: regulator: Let drivers know when they
use the stub API); and use IS_ERR_OR_NULL() to handle the stub function 
correctly.

Changes since v1:
  - Use IS_ERR_OR_NULL() to correctly handle the stub regulator_get()
  - Put the short commit message of be1a50d so it is easier to see what it is 
    about, for the long commit and the actual code changes the git history can 
    be queried.

Thanks,
