This makes dmc driver possible to register a system status notifier and
other drivers possible to call the notifier call-back easily, so that
the dmc driver can change frequency according to different system status.

In rockchip_clk_register_ddrclk,
ifdef CONFIG_ARM
if (!psci_smp_available())
return NULL;
endif
Add "__init" for rockchip_clk_register_ddrclk() to match with
psci_smp_available().

ARM32 system can run without trustos,
we should prevent arm_smccc_smc being called in such system.

Because uart does not have high requirements
for the clk Jitter, the fractional frequency
divider does not need to meet the 20-fold relationship.
(If uart clk rate < 24M,Use 24M as the fractional
clock source.)

Numerator is greater than 4,the clk jitter is better.

NPLL should provide clock for vopl dclk on px30, and its rate will be
changed according to vopl dclk rate, so GPU can't use npll as parent
on px30.

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.
