regulator: rtq6752: Enclose 'enable' gpio control by enable flag 

Fix 'enable' gpio control logic from the below cases if it's specified.

1. All off and both are sequentially controlled to be on.
The 'enable' gpio control block to be called twice including the delay time.

2. Both are on and one is preparing to be off.
The 'enable' gpio control low before register cache is configured to be true.
