RV1126 set 3.3V before regulator disable.
Do a fix to rockchip io-domain, follow this orders:
* system running state
-> io-domain vsel to 3.3V (actually is done by event-disable)
-> regulator_enable
-> vsel change according to regulator voltage
* system running state
-> regulator_disable
-> io-domain vsel to 3.3V
The bug only instance on RV1126, and tested on RV1126 EVB DDR3 V10.

A clock driver for a arm SoC should depend on ARM, but for a arm64 SoC,
the driver should not depend on ARM64 since SoC could used as 32bit,
such as the RK3308 aarch32 platform.

Sync driver with v4.4 and v4.19, support rk3308bs/px30s/rk3326s whose io
type is new called as smic type.
The smic type io configure drive strength with 3 bit, the highest bit is
from slew rate bit for the origin io type, that also means the smic io
not support slew rate setting.
The drive strength setting difference:
regval RK3308B RK3308BS
0 2mA 0mA
1 4mA 2mA
2 8mA 4mA
3 12mA 6mA
4 6mA
5 8mA
6 10mA
