cmd: pmic: annotate switch/case fallthrough

The argument parsing code in the pmic command uses an implicit switch/case
fallthrough to handle the common part of having one or two arguments.

Add our "fallthrough;" statement-like macro before the second branch in
the parsing code, to avoid a warning when GCC's -Wimplicit-fallthrough
warning option is enabled.
