[PATCH] clk: mediatek: fix cppcheck error for uninitialized variable

From: Kishan Dudhatra <kishan.dudhatra at siliconsignals.io>

cppcheck reports below warning

clk/mediatek/clk-fhctl.c:206:27:
error: Uninitialized variable: pll_postdiv [uninitvar]
if (postdiv && postdiv < pll_postdiv)

This is due to uninitialization of variable pll_postdiv,
which is now initialized as part of this patch.
