Problem:
PDD needs to be enabled by default and print a line
of log to the serial port when triggered.
Solution:
Added pdd_monitor driver, which mainly implements
the following functions:
1. Print log to the serial port when triggered.
2. Provide a simple interface for user space.

Problem:
If the interval between two sampling points is more than 100 milliseconds,
the sampling value may not change with the actual voltage.
Solution:
A workaround is to enable ADC_EN before sampling and disable it after
sampling is completed.
