Subject: [PATCH 0/3] riscv: spacemit: add gpio support for K1 SoC

The gpio controller of K1 support basic GPIO functions,
which capable of enabling as input, output. It can also be used
as GPIO interrupt which able to detect rising edge, failing edge,
or both. There are four GPIO banks, each consisting of 32 pins.

The GPIO driver request one clock source from APBC block,
In this series, I haven't added the clock support, instead plan
to fix it after clock driver is implemented/merged.

The GPIO docs of K1 SoC can be found here, chapter 16.4 GPIO [1]

Note, this patch need two prerequisite series, basic dt[2] and pinctrl[3]
