Subject: [PATCH] remoteproc: move rproc_da_to_va declaration to remoteproc.h

From: Suman Anna <s-anna@...com>

The rproc_da_to_va() API is an exported function, so move its
declaration from the remoteproc local remoteproc_internal.h
to the public remoteproc.h file.

This will allow drivers outside of the remoteproc folder to be
able to use this API.

Note: I previously posted this patch as part of a series:
[PATCH 00/11] soc: ti: wkup_m3_ipc: support vtt toggle, io isolation & voltage scaling
https://lore.kernel.org/linux-omap/20220219215328.485660-1-dfustini@baylibre.com/

I was advised to break that series up into smaller pieces, so I am
submitting this patch individually. I will in the future post a series
to support i2c voltage scaling which will utilize rproc_da_to_va() from 
drivers/soc/ti/wkup_m3_ipc.c
