[PATCH] watchdog: imx2_wdt: set variables imx_wdt* storage-class-specifier to static

[Tom Rix]

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

These variables are only used in one file so should be static.
