drm/i915: Add more wrapper for fixed_point_16_16 operations
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.
Changes from V1:
- Rename wrapper as per Matt's comment
Changes from V2:
- Fix indentation
