We need to put the power status of HEVC IP into IDLE unless
we can't reset that IP or the SoC would crash down.
rockchip_pmu_idle_request(dev, true)---> enter idle
rockchip_pmu_idle_request(dev, false)---> exit idle

There is a lower power dissipation requirement for some products, like
battery ipc, bell, etc... We have to gate cpll/hpll to reduce power
dissipation.

Rockchip socs often have some tiny number of muxes not controlled from
the core clock controller but through bits set in the pmugrf.
Use MUXPMUGRF() to cover this special clock-type.

This patch registers two composite clocks for this branch type,
and make them become brother clock for each oher.

Some composite clocks may have the same parent clock, if one clock change
the parent clock rate, the other clock rate may too large, so add a
brother clock in composite that the other clock also can be changed when
parent rate is changed.

The CLK_SET_RATE_PARENT flag make the parent clock and the child clk is 1:1.
If the DCLK frequency is too low, the PLL frequency will be very
low, which will affect the output waveform quality of PLL, and PLL
locking may be abnormal, so add a new COMPOSITE_DCLK clock-type to handle
that.

From Rockchips fractional divider usage, some clocks can be generated
by fractional divider, but the input clock frequency of fractional
divider should be less than a specified value.
