Initialize the 'regmap_rtc' on S2MPA01 to some sane value. Sane at least
for S5M87X chipsets, not S2MPS/S2MPA but it won't be used because
rtc-s5m driver does not support S2MPA01.
This fixes following error:
drivers/mfd/sec-core.c:342:45: warning: ‘regmap_rtc’ may be used uninitialized in this function [-Wuninitialized]
