regulator: s2mps11: Simplify expression used in BUILD_BUG_ON
Following BUILD_BUG_ON using a variable fails for some of the compilers and optimization levels (reported for gcc 4.9): var = ARRAY_SIZE(s2mps15_regulators); BUILD_BUG_ON(S2MPS_REGULATOR_MAX < var); Fix this by using ARRAY_SIZE directly. Additionally add missing BUILD_BUG_ON check for S2MPS15 device (the check ensures that internal arrays are big enough to hold data for all of regulators on all devices).
