When CONFIG_NWBUTTON_REBOOT is disabled, we get a warning about
an unused variable:
drivers/char/nwbutton.c:37:12: warning: 'reboot_count' defined but not used [-Wunused-variable]
static int reboot_count = NUM_PRESSES_REBOOT; /* Number of presses to reboot */
Using if(IS_ENABLED()) instead of #ifdef around the user makes the
code nicer to read and avoids the warning.
