Log Message:
implement TSADC driver for rockchip RK3328 and RK3399.  so far, only
tested on RK3399 but the RK3328 looks mostly the same and has a good
chance of working too.

add clock entries for "clk_tsadc" and "pclk_tsadc" to cru.

exports "CPU" and "GPU" temp sensors.  these currently limited to 5
degC resolution but can be reduced to sub 1 degC resolution with some
interpolation.

todo list:

- handle setting various temp values
- add interpolation between the 5degC intervals in sample data
- handle DT trips/temp value defaults
- interrupts aren't triggered (test by lowering warn/crit values),
  and once they work, make the interrupt do something
- test on RK3328, and port to other rockchips (will require moving
  some part into per-chipset sections, such as code<->temp tables)

thanks to jmcneill for help.
