  J721S2 has two instances of 8 channel ADCs in MCU domain. Add DT nodes
for 8 channel ADCs for J721S2.

Enable ADCs present on J721S2 soc.

Node names should be generic, so "adc"

tscadc is just a wrapper node. The actual adc node is inside of tscadc node.

Hi, please drop this patch since the interrupt values supplied for 
tscadc are incorrect.
