watchdog: booke_wdt: fix build - unconstify watchdog_info

commit 42747d712d ("[WATCHDOG] watchdog_info
constify") introduced the following build failure:

   CC      booke_wdt.o
 booke_wdt.c: In function 'booke_wdt_init':
 booke_wdt.c:220: error: assignment of read-only variable 'ident'

Fix this by removing 'const' qualifier from watchdog_info struct.
