Use kmemdup instead of kmalloc + memcpy.

It is not preferable to have the allocated pages for carveout
memories freed before they are unmapped. The code that deals
with the cleanup of carveout memories is therefore moved after
the corresponding mapping entries were cleaned up.This is mostly a no-op since the remote processors are already
stopped when the cleanup function is called, but this will make
the cleanup code follow the exact reverse path of allocation.Signed-off-by: Suman Anna

The mailbox hardware (in OMAP) uses a queued mailbox interrupt
mechanism that provides a communication channel between processors
through a set of registers and their associated interrupt signals
by sending and receiving messages.The OMAP mailbox framework/driver code is moved to be under
drivers/mailbox, in preparation for adapting to a common mailbox
driver framework. This allows the build for OMAP mailbox to be
enabled (it was disabled during the multi-platform support).As part of the migration from plat and mach code:
- Kconfig symbols have been renamed to build OMAP1 or OMAP2+ drivers.
- mailbox.h under plat-omap/plat/include has been split into a public
and private header files. The public header has only the API related
functions and types.
- The module name mailbox.ko from plat-omap is changed to
omap-mailbox.ko
- The module name mailbox_mach.ko from mach-omapX is changed as
mailbox_omap1.ko for OMAP1
mailbox_omap2.ko for OMAP2+Cc: Tony Lindgren

Pull remoteproc update from Ohad Ben-Cohen:
- Some refactoring, cleanups and small improvements from Sjur
Brændeland. The improvements are mainly about better supporting
varios virtio properties (such as virtio's config space, status and
features). I now see that I messed up while commiting one of Sjur's
patches and erroneously put myself as the author, as well as letting
a nasty typo sneak in. I will not fix this in order to avoid
rebasing the patches. Sjur - sorry!- A new remoteproc driver for OMAP-L13x (technically a DaVinci
platform) from Robert Tivy.- Extend OMAP support to OMAP5 as well, from Vincent Stehlé.

Patch a62a6e98 "ARM: OMAP2+: Disable code that currently does not work
with multiplaform" makes the OMAP_MBOX_FWK option depend on !MULTIPLATFORM,
which means we cannot simply select that symbol from OMAP_REMOTEPROC.Turning the 'select' into 'depends on' ensures that all dependencies
are correct until OMAP_MBOX_FWK loses its dependency.Without this patch, building allmodconfig results in:

When a remote processor crash is detected, this mechanism will remove
all virtio children devices, wait until their drivers let go, hard

relevant virtio children devices re-added). Essentially the entire
software stack is reset, together with the relevant hardware, so
users don't have to reset the entire phone.- STE Modem driver is added - by Sjur Brændeland
