zephyr: npcx_evb: Enable ADC
This CL enables 5 ADC channels for npcx7/9_evb. BUG=none BRANCH=none TEST='adc' console command ``` uart:~$ adc ADC0 = 2813 mV ADC1 = 2813 mV ADC2 = 2813 mV ADC3 = 2813 mV ADC4 = 2813 mV ``` Signed-off-by: Wealian Liao <whliao@nuvoton.corp-partner.google.com> Change-Id: I08d60dc732f7388642a54eec090ef7bf15760a2a Reviewed-on: https://chromium-review.googlesource.com/c/chromiumos/platform/ec/+/3063103 Reviewed-by: Keith Short <keithshort@chromium.org> Commit-Queue: Keith Short <keithshort@chromium.org>
