The maple tree register cache is based on a much more modern data structure
than the rbtree cache and makes optimisation choices which are probably
more appropriate for modern systems than those made by the rbtree cache.

After commit b8a1a4cd5a ("i2c: Provide a temporary .probe_new()
call-back type"), all drivers being converted to .probe_new() and then
03c835f498 ("i2c: Switch .probe() to not take an id parameter") convert
back to (the new) .probe() to be able to eventually drop .probe_new() from
struct i2c_driver.

This follows on the change ("regulator: Set PROBE_PREFER_ASYNCHRONOUS
for drivers that existed in 4.14") but changes regulators didn't exist
in Linux 5.10 but did exist in Linux 5.15.

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.

Reg will be reset in below two conditions.
1. 'Enable' pin from H to L.
2. Both PAVDD and NAVDD are all disabled.
And 'Enable' pin also control i2c communication capability.
This patch is to Seperate the if condition in enable/disable callback for
reg cache manipulation.
