drivers: marvell: add thermal sensor driver and expose it via SIP service
Since the dfx register set is going to be marked as secure (in order to
protect efuse registers for non secure access), accessing thermal
registers which are part of dfx register set, will not be possible from
lower exception levels. Due to above expose thermal driver as a SiP
service. This will allow Linux and U-Boot thermal driver to initialise
and perform various operations on thermal sensor.
The thermal sensor driver is based on Linux
drivers/thermal/armada_thermal.c.
