Remove the parameter from the call in rproc_add_virtio_dev().

Fix typo in comments.
Change returned error from ENOMEM to EINVAL as
not dealing with memory allocation.
Remove carveout forced da update and return an error
when no configuration match

With rproc_alloc_registered_carveouts() introduction, carveouts are
allocated after resource table parsing.
rproc_da_to_va() may return NULL at trace resource registering.
This patch modifies trace debufs registering to provide device address
(da) instead of va.
da to va translation is done at each trace buffer access
through debugfs interface.

Correct remoteproc core behavior when memory carveout device
address is fixed in resource table and rproc device doesn't have
associated IOMMU.
Current returned error is breaking legacy on TI platforms.
This patch restores previous behavior. It adds a warn message when
allocation doesn't fit carveout request, but doesn't stop rproc_start()
sequence anymore.

Today resource table supports only 32bit address fields.
This is not compliant with 64bit platform for which addresses
are cast in 32bit.
This patch adds warn messages when address cast is done.

As dma member of struct rproc_mem_entry is dma_addr_t, no
need to cast in u32.

With introduction of rproc_alloc_registered_carveouts() which
delays carveout allocation just before the start of the remote
processor, rproc_da_to_va() could be called before all carveouts
are allocated.
This patch adds a check in rproc_da_to_va() to return NULL if
carveout is not allocated.
