PCI: qcom-ep: Disable MHI RAM data parity error interrupt for SA8775P SoC
SA8775P SoC has support for the hardware parity check feature on the MHI
RAM (entity that holds MHI registers, etc.) But due to a hardware bug in
the parity check logic, the data parity error interrupt is getting
generated all the time when using MHI. So the hardware team has suggested
disabling the parity check error to work around the hardware bug.
Mask the parity error interrupt in PARF_INT_ALL_5_MASK register.
