Subject: [PATCH 0/2] riscv: spacemit: add pinctrl support to K1 SoC

This series adds pinctrl support to SpacemiT's K1 SoC which
has feature compatible with pinctrl-single driver, then later
add pinctrl property for Bananapi-F3 uart device.

The pinctrl docs of K1 can be found here[1], and this dts is largely
converted from vendor's pinctrl code[2]

Note, ideally, we should map raw drive strength value to more user
readable current value, still need to figure out this..
