regulator: Fixes for v6.6

Two things here, one is an improved fix for issues around freeing
devices when registration fails which replaces a half baked fix with a
more complete one which uses the device model release() function
properly.  The other fix is a device specific fix for mt6358, the driver
said that the LDOs supported mode configuration but this is not actually
the case and could cause issues.
