Series drm/amd/display: Reduce stack usage for clang | expand

Commit Message

Several of the arguments are identical between the two call sites and
they can be accessed through the 'struct vba_vars_st' pointer. This
reduces the total amount of stack space that
dml32_ModeSupportAndSystemConfigurationFull() uses by 208 bytes with
LLVM 16 (1936 -> 1728), helping clear up the following clang warning:

  drivers/gpu/drm/amd/amdgpu/../display/dc/dml/dcn32/display_mode_vba_32.c:1721:6: error: stack frame size (2152) exceeds limit (2048) in 'dml32_ModeSupportAndSystemConfigurationFull' [-Werror,-Wframe-larger-than]
  void dml32_ModeSupportAndSystemConfigurationFull(struct display_mode_lib *mode_lib)
       ^
  1 error generated.

Additionally, while modifying the arguments to
dml32_CalculatePrefetchSchedule(), use 'v' consistently, instead of 'v'
mixed with 'mode_lib->vba'.
