            Bug ID: 224481
           Summary: Add H3 to aw_sid driver for Allwinner SoC

SID driver patch

For the correct operation of the aw_thermal driver, a thermal calibration
function is required, presented in the aw_sid driver. However, the driver d=
oes
not support H3 SoC.
It is known that H3 SoC has a hardware bug when reading SID (root key) - see
http://linux-sunxi.org/SID_Register_Guide#SID_PRCTL

I suggest a patch that more correctly implements the aw_sid driver.

DTS to enable the driver device:
...
sid: eeprom@1c14000 {
       compatible =3D "allwinner,sun8i-h3-sid";
       reg =3D <0x01c14000 0x400>;
};
...

The driver is tested on H2+ SoC (OrangePi Zero)
