[PATCH] watchdog: imx2_wdg: Declare local symbols static

[Guenter Roeck <linux@xxxxxxxxxxxx>]

0-day complains:

drivers/watchdog/imx2_wdt.c:442:22: sparse:
	symbol 'imx_wdt' was not declared. Should it be static?
drivers/watchdog/imx2_wdt.c:446:22: sparse:
	symbol 'imx_wdt_legacy' was not declared. Should it be static?

Declare as static variables.

Fixes: e42c73f1ef0d ("watchdog: imx2_wdg: suspend watchdog in WAIT mode")
