Subject: regulator: pfuze100: A few small questions

Hi Robin,
2 questions about the code in pfuze100 driver:

1)
Both PFUZE100_REVID and PFUZE100_FABID are defined as 0x3.
So I'm wondering if it's a typo in one of the register address?
If they are actually the same register, we don't need to read the same
register twice in pfuze_identify().

2)
What is the the purpose of stby_reg and stby_mask?
Seems current code does not use it?
