LF-2202-2: regulator: pca9450: add enable_value for all bucks
BuckX enable mode
00b = OFF
01b = ON by PMIC_ON_REQ = H
10b = ON by PMIC_ON_REQ = H && PMIC_STBY_REQ = L
11b = Always ON
For such enable mode, enable_value should be clearly set in requlator desc,
00/11 is not enough, correct it now for different bucks. For example, buck2
is designed for vddarm which could be off in 'PMIC_STBY_REQ = H' after kernel
enter suspend, so should be set '10b' as ON, while others is '01b' as ON.
All are the same as the default setting which means bucks no need to be
enabled again during kernel boot even if they have been enabled already after
pmic on.
