An earlier commit populated the OPP tables from the "required-opps"
property, this commit populates the individual OPPs. This is repeated
for each OPP in the OPP table and these populated OPPs will be used by

Multiple generic power domains for a device are supported with the help

Convert the driver to use the timer_of helpers.
This allows to remove custom proprietary structure,
factors out and simplifies the code.

This patch adds a new driver for system timer on the Mediatek SoCs.
Changes since v3:
- Use the same binding style for both GPT and System Timer.
- Use timer_of.of_clk->period instead of private structure.
- Arrange patches to contain system timer changes in patch 5/5 only.
Changes since v2:

This patch adds a new "System Timer" on the Mediatek SoCs.
The System Timer is introduced as an always-on timer being
clockevent device for tick-broadcasting.
For clock, it is driven by 13 MHz system clock.
The implementation uses the system clock with no clock
source divider.
For interrupt, the

The HPLL can be configured through a register (SCU24), however some
platforms chose to configure it through the strapping settings and do
not use the register. This was not noticed as the logic for bit 18 in
SCU24 was confused: set means programmed, but the driver read it as set
means strapped.
