[PATCH v3 0/2] Add StarFive JH7110 SoC shutdown and reboot ops

[Minda Chen]

Test board is JH7110 visionfive v2 board. shutdown and reboot function
require to access axp15060 PMIC through i2c.

patch1 is i2c driver. i2c ip is designware. dw_i2c.c includes designware
i2c minimal driver which can be used by other platform.
fdt_i2c_dw.c parse i2c register base and other information.

patch2 is JH7110 visionfive2 board reboot and shutdown ops.
The i2c clk will be disabled by kernel i2c driver in power off progress
(suspend ops).
