Revert "src/drivers/intel/wifi: Add a W/A for Intel ThP2 9260"
This reverts commit 3afb84a24583f5dee9fb407f11b32253d59392bf.
Reason for revert: This is causing issues with the PCIe link
and the system is unable to enter S0ix. Until it can be fixed
in coreboot revert the change here that is not working properly.
BUG=b:124264120
