There can be up to eight optional device functional gate gate clocks for
each clkctrl instance in clkctrl register bits 8 to 15. Some of them are
only needed for module level reset while others may always be needed
during use. Let's add support for those and update the binding doc
accordingly.
Note that the optional clkctrl mux and divider clocks starting at bit 20
can be directly mapped to the child devices, and ti-sysc does not need to
manage those.
And as GPIOs need the optional clocks for reset, we can now add it with
SYSC_QUIRK_OPT_CLKS_IN_RESET.

Hardware needs a delay between setting an initial (non-zero) PWM and
enabling the backlight using GPIO. The post-pwm-on-delay-ms specifies
this delay in milli seconds. Hardware also needs a delay between disabing
the backlight using GPIO and setting PWM value to 0. The pwm-off-delay-ms
is this delay in milli seconds.

None of the existing platforms connect the R/B pin to a GPIO (they all
