[PATCH] regulator MAX8998/LP3974 Bufgix: accessing array out of bound.

[MyungJoo Ham]

The previous driver may access ldo_voltage_map[] out of its bound at
probe function at line 790 (drivers/regulator/max8998.c). This patch
allocates an entry for every regulator in order to avoid accessing
out-of-bounds.
