Subject: [PATCH v3 4/4] remoteproc: core: Remove unused export of
 rproc_va_to_pa

commit 086d08725d34 ("remoteproc: create vdev subdevice with specific dma
memory pool") added an export for rproc_va_to_pa. However, since its
introduction, this symbol has not been used by any loadable modules. It
remains only referenced within remoteproc_virtio.c, which is always built
together with remoteproc_core.c.

As such, exporting rproc_va_to_pa is unnecessary, so remove the export.

No functional changes.
