bus: mhi: pci_generic: Fix inbound IPCR channel

commit b8a97f2a upstream.

The qrtr-mhi client driver assumes that inbound buffers are
automatically allocated and queued by the MHI core, but this
doesn't happen for mhi pci devices since IPCR inbound channel is
not flagged with auto_queue, causing unusable IPCR (qrtr)
feature. Fix that.
