Subject: watchdog: kempld_wdt: Fix bit mask definition
From: Jingoo Han <jg1.han@xxxxxxxxxxx>
commit 4c4e45669de475573b15d968a6dca8d00124c9ad upstream.
STAGE_CFG bits are defined as [5:4] bits. However, '(((x) & 0x30) << 4)'
handles [9:8] bits. Thus, it should be fixed in order to handle
[5:4] bits.
