PCI: qcom: Define some PARF params needed for ipq8064 SoC

commit 5149901e9e6deca487c01cc434a3ac4125c7b00b upstream.

Set some specific value for Tx De-Emphasis, Tx Swing and Rx equalization
needed on some ipq8064 based device (Netgear R7800 for example). Without
this the system locks on kernel load.
