Nathan Chancellor 563dfbefdf drm/amd/display: Reduce number of arguments of dcn30's CalculateWatermarksAndDRAMSpeedChangeSupport()

CalculateWatermarksAndDRAMSpeedChangeSupport() has a large number of
parameters, which must be passed on the stack. Most of the parameters
between the two callsites are the same, so they can be accessed through
the existing mode_lib pointer, instead of being passed as explicit
arguments. Doing this reduces the stack size of
dml30_ModeSupportAndSystemConfigurationFull() from 1912 bytes to 1840
bytes building for x86_64 with clang-22, helping stay under the 2048
byte limit for display_mode_vba_30.c.

Additionally, now that there is a pointer to mode_lib->vba available,
use 'v' consistently throughout the entire function.
