thermal/drivers/armada: Add support for AP807 thermal data 



Add support for the AP807 die thermal data. This is the same as AP806,
except for the coefficients.

ap807 values taken from TSENSE_ADC_16FFC spec, which says:
	T(in Celsius) = T(code)*TSENE_GAIN+TSENE_OFFSET
where in default:
	TSENE_OFFSET = 128.9
	TSENE_GAIN = 0.394
