[PATCH 16/45] drm/amd/display: Fix incorrect size calculation for loop

[Tom Chung]

From: Alex Hung <alex.h...@amd.com>

[WHY]
fe_clk_en has size of 5 but sizeof(fe_clk_en) has byte size 20 which is
lager than the array size.

[HOW]
Divide byte size 20 by its element size.

This fixes 2 OVERRUN issues reported by Coverity.
