r356148:
arm64: rockchip: rk808: Add remaining regulators
The RK808 driver was missing the LDO and switch regulators.
Add support for them.
Reviewed by: mmel
Differential Revision: https://reviews.freebsd.org/D22852
r356149:
arm64: rockchip: Add driver for the io domain
This driver configure the registers in the GRF according to the value
of the regulators for the platform.
Some IP can run with either 3.0V or 1.8V, if we don't configure them
correctly according to the external voltage used they will not work.
It's only done at boot time for now and might be needed at runtime for
IP like sdmmc.

r356277:
arm64: rockchip: Add a module for rk_spi
The spi node doesn't lives under a simple-bus compatible node so we need
OFWBUS_PNP_INFO instead of SIMPLEBUS_PNP_INFO.
