The div offset of some clocks are different from their mux offset
and the COMPOSITE clock-type require that div and mux offset are
the same, so add a new COMPOSITE_DIV_OFFSET clock-type to handle that.

The power domains are supplied by regulators. Add support for them so
that the regulators are properly turned on before a domain is powered up
and turned off when a domain is powered down.

And it requires setting the tshut polarity before select pinctrl.

Tsadc has a tshut pin which is designed to reset the pmic or soc,
when the temperature inside soc is too high. we should switch off
the tshut function and change the pin to gpio function in reboot
process, eg, software reset. If not, the tsadc module will WRONGLY
pull high the tshut pin during its reset process and then WRONGLY
reset the pmic or soc, which incurred a hardware reset. The hardware
reset will reset everything inside soc, even includes the power on
reason flag, which is set by software before reboot process.
we also change over-temperature protection mode to cru mode,
since the tshut pin have be changed to gpio function.

We find an usb phy 480MHz clk prepare fail issue on PX30/RK3326
platforms with RK819 PMIC. On PX30/RK3326 platforms, we set the
usb480m clk to critical because GPU 480M is from usb480m and the
source clocks should be always on. And the usb phy 480MHz clk is
parent of usb480m clk, so the clk framework will prepare the usb
phy 480MHz clk when register it.
This logic works well if the usb phy probe only once. But if the
usb phy needs to probe twice or more because of some reasons (e.g.
fail to get vbus regulator from RK819), the usb phy 480MHz clk will
be unregistered and registered again, however, the clk framework
doesn't prepare the usb phy 480MHz clk except the first time register
operation. So we move the 480MHz clk register to the end of probe,
and make sure only register it once.
