drm/amd/display: Calculate swizzle mode using bpp during validation
[Why]
Previously bandwidth validation was failing because swizzle mode was not
initialized during plane_state allocation. The swizzle mode was
calculated using pixed format which is how swizzle mode is initially
calculated in addrlib.
[How]
* Set default swizzle mode for validation to DC_SW_UNKNOWN
* Created new function in dcn10_assign_swizzle_mode which sets the
plane swizzle mode based on selected pixed format
* Added the call of assign_swizzle_mode into dc_validate_global_state
* Set failsafe swizzle mode back to DC_SW_LINEAR
