SpacemiT K1 pinctrl requires two clocks in order to be functional,
also one reset line from hardware persepective.

In this series, adding clock property in dt-binding, and activate
them in the driver. But for reset, making it optional for now.

Notice that, devm_clk_get_optional_enabled() API has be choosed,
which will make old dtb blob still functioinal with new kernel.

For DT part patch, I plan to submit after clock driver merged.
This may result dtb warnings in this version due to the mising
clock property in pinctrl dt node.
