Andrew Turner 59f6ddb2bc Use pmap_qenter in the N1SDP PCIe driver
In the Neoverse N1 SDP PCIe driver we need to map a page shared
between the firmware and the kernel. Previously we would use
pmap_kenter for this, however as this is not standardised between
architectures switch to the common pmap_qenter.

While here fix the error handling code to clean up on failure.
