3.3V fixed regulator does not belong to TPS node - as a result
the fixed regulator is never probed and MMC is continually deferred due
to lack of regulator.

Move the fixed regulator to be at root of platform.

After: http://pastebin.com/149FWujf
notice how "vmmcsd_fixed: 3300 mV " does not appear in the log before the patch.
