This patch adds few wrapper to perform fixed_point_16_16 operations mul_round_up_u32_fixed16 : Multiplies u32 and fixed_16_16_t variables & returns u32 result with rounding-up. mul_fixed16 : Multiplies two fixed_16_16_t variable & returns fixed_16_16 div_round_up_fixed16 : Perform division operation on fixed_16_16_t variables & return u32 result with round-off div_round_up_u32_fixed16 : devide uint32_t variable by fixed_16_16 variable and round_up the result to uint32_t. These wrappers will be used by later patches in the series.
