media: staging: rkisp1: replace two identical macros with one

The two macros RKISP1_CIF_ISP_LSC_{GRAD/SIZE}_TBL_SIZE have
the same value which is the number of sectors in the grads
and size parameters. Therefore there is no need for two
different macros. Replace them with one macro
RKISP1_CIF_ISP_LSC_SECTORS_TBL_SIZE. Also use the macro
when iterating the arrays instead of hardcoded '4'.
