changes since v1:
- added missing pinctl-names for gpio-leds
- drop min-/max voltage for rk808's regulator swtiches
- fix bluetooth max-speed: 1500000 => 15000000
- replace deprecated "host-wakeup-gpios" with "host-wake" interrupt for
bluetooth
- alignment of property-order for nodes of the same type
