clk: qcom: gcc-msm8994: Fix gpll4 width

[ Upstream commit 71021db1c532c2545ae53b9ee85b37b7154f51d4 ]

The gpll4 postdiv is actually a div4, so make sure that Linux is aware of
this.

This fixes the following error messages:

 mmc1: Card appears overclocked; req 200000000 Hz, actual 343999999 Hz
 mmc1: Card appears overclocked; req 400000000 Hz, actual 687999999 Hz
