mb/google/kahlee: Remove #include <soc/smi.h>

Because of struct sci_source table of events that have to generate SCI or
SMI, <soc/smi.h> was included to kahlee/grunt gpio.c files. However, new
code transfered most of SCI/SMI/interrupt programming (with exception of
events not associated to a GPIO pin), and therefore smi.h is now included
by gpio.h. It was also added to some other files where they are not needed.
Only smihandler.c truly needs it. Remove the includes.

BUG=b:78139413
TEST=build and boot grunt.
