Manivannan Sadhasivam 200b8f85f2 PCI: qcom: Disable write access to read only registers for IP v2.9.0 
In the post init sequence of v2.9.0, write access to read only registers
are not disabled after updating the registers. Fix it by disabling the
access after register update.

While at it, let's also add a newline after existing dw_pcie_dbi_ro_wr_en()
guard function to align with rest of the driver.
