[PATCH] regulator: s2mps11: Fix wrong calculation of register offset

[PATCH] regulator: s2mps11: Fix wrong calculation of register offset

[Chanwoo Choi]

From: Jonghwa Lee <jonghwa3.lee@samsung.com>

This patch adds missing registers('BUCK7_SW' & 'LDO29_CTRL'). Since BUCK7 has
1 more register (BUCK7_SW) than others, register offset should
be added one more for which has bigger address than BUCK7 registers.
