drm/amd/display: Remove redundant ternary operation

Browse Source 
[WHY]
Coverity analysis flagged this ternary operation as
DEADCODE.

Since 'total_y_free_entry' is initialized as 0x200 and
'total_c_free_entry' is initialized as 0x140, and they
never change values before the ternary operator, so
'total_y_free_entry' is always greater 'total_c_free_entry',
'so small_free_entry' is always set to 'total_c_free_entry'.

[HOW]
Replace the ternary operator with the variable declaration.
