rockchip platform have a protocol to pass the kernel reboot
mode to bootloader by some special registers when system reboot.
By this way the bootloader can take different action according
to the different kernel reboot mode, for example, command
"reboot loader" will reboot the board to rockusb mode, this is
a very convenient way to get the board enter download mode.
And Android system also use this protocol to pass "recovery"、
“fastboot” reboot mode to bootloader. In upstream land, We found
tegra platform also use this mechanism.

Before this version, I have sent two Series, which can be found
at [0] [1]
[0] https://patchwork.kernel.org/patch/7140751/
[1] https://patchwork.kernel.org/patch/7153531/

Changes in v3:
 - rename a pinctrl node in rk3288-veyron, the original name will be
   used in the incoming reboot notifier driver
 - add dt binding
 - move from mach-rockchip to drivers/soc/rockchip, as the tegra does
 - use dts pass the related register
 - add DT node

Changes in v2:
  - check cpu dt node
  - remove a unnecessary of_put_node in function rockchip_get_pmu_regmap
  - fix a align issue
  - use reboot_notifier instead of restart_handler
