Add support for the ESWIN EIC7700 PVT (Process, Voltage, Temperature)
sensor

Features:
The driver supports monitoring of process, voltage and temperature
parameters through the hardware monitoring subsystem. It provides an
access to the sampled Temperature and Voltage.

Test:
Tested this patch on the SiFive HiFive Premier P550 (which uses the ESWIN
EIC7700 SoC).
