clk: xgene: Add missing parenthesis when clearing divider value

Browse Source 
commit 0f4c7a138d upstream.

In the initial fix for non-zero divider shift value, the parenthesis
was missing after the negate operation. This patch adds the required
parenthesis. Otherwise, lower bits may be cleared unintentionally.
