watchdog: kempld_wdt: Add __user annotation
Added __user annotation to fix the following sparse warnings.
Also, it makes 'kempld_prescaler' static because it is used
only in this file.
drivers/watchdog/kempld_wdt.c:70:11: warning: symbol 'kempld_prescaler' was not declared. Should it be static?
drivers/watchdog/kempld_wdt.c:364:23: warning: incorrect type in initializer (different address spaces)
drivers/watchdog/kempld_wdt.c:364:23: expected int const [noderef] <asn:1>*register __p
drivers/watchdog/kempld_wdt.c:364:23: got int *<noident>
