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
