[PATCH AUTOSEL 6.0 38/39] drm/amd/display: Use new num clk levels struct for max mclk index

[Sasha Levin]

From: Dillon Varone <Dillon.Varone at amd.com>

[ Upstream commit e667ee3b0c049bf0c69426879586a2572bb28d26 ]

[WHY?]
When calculating watermark and dlg values, the max mclk level index and
associated speed are needed to find the correlated dummy latency value.
Currently the incorrect index is given due to a clock manager refactor.

[HOW?]
Use num_memclk_level from num_entries_per_clk struct for getting the correct max
mem speed.
