This adds the base driver that implements the serial protocol via serdev and additionally hooks into the poweroff handlers to turn off the parts of the system not supplied by the general PMIC. Turning off (at least the TSx33 devices using Rockchip SoCs) consists of two separate actions. Turning off the MCU alone does not turn off the main SoC and turning off only the SoC/PMIC does not turn off the hard-drives. Also if the MCU is not turned off, the system also won't start again until it is unplugged from power. So on shutdown the MCU needs to be turned off separately before the main PMIC. The protocol spoken by the MCU is sadly not documented, but was obtained by listening to the chatter on the serial port, as thankfully the "hal_app" program from QNAPs firmware allows triggering all/most MCU actions from the command line. The implementation of how to talk to the serial device got some inspiration from the rave-sp servdev driver.
