[PATCH 6.11 095/107] drm/amd/pm: print pp_dpm_mclk in ascending order on SMU v14.0.0

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

6.11-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Tim Huang <tim.huang@amd.com>

commit df0279e2a1c0735e8ca80c5df8d9f8f9fc120b4a upstream.

Currently, the pp_dpm_mclk values are reported in descending order
on SMU IP v14.0.0/1/4. Adjust to ascending order for consistency
with other clock interfaces.
