drm/amd/display: Reduce number of arguments of dml32_CalculateWatermarksMALLUseAndDRAMSpeedChangeSupport()

Most of the arguments are identical between the two call sites and they
can be accessed through the 'struct vba_vars_st' pointer created at the
top of dml32_ModeSupportAndSystemConfigurationFull(). This reduces the
total amount of stack space that
dml32_ModeSupportAndSystemConfigurationFull() uses by 216 bytes with
LLVM 16 (2152 -> 1936), 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_CalculateWatermarksMALLUseAndDRAMSpeedChangeSupport(), use 'v'
consistently, instead of 'v' mixed with 'mode_lib->vba'.
