endpoint from the server which the client queries

+Subject: 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.
