regulator: rt6245: Restore state on enable failure

Browse Source 
Currently, if regcache_sync() fails after the enable GPIO has been
asserted, the driver returns with enable_gpio still set high and
regcache_cache_only() left disabled. This leaves the device state
inconsistent with the disabled state, where the enable GPIO is low and
cache_only is enabled.
On failure, restore the original state by setting cache_only back to
true and driving the enable GPIO low before returning the error.
