dt-bindings: display: sprd,sharkl3-dsi-host: Fix missing clocks constraints

commit 2558df8c upstream.

'minItems' alone does not impose upper bound, unlike 'maxItems' which
implies lower bound.  Add missing clock constraint so the list will have
exact number of items (clocks).

Fixes: 2295bbd3 ("dt-bindings: display: add Unisoc's mipi dsi controller bindings")
