Guybrush: Zephyr: Add thermistors
Add the two thermistor sensors on the charger and memory. Note that
memory read will be different from CrosEC version, since it was
previously going through a chipset check in the board code.
Also adjust ADC node names to follow Linux convention with a dash.
BRANCH=None
BUG=b:195137794
TEST=load onto guybrush, confirm reasonable looking temperatures
