On CN10K platform transmit/receive buffer alloc and free from/to
hardware had changed to support burst operation. Whereas pervious
silicon's only support single buffer free at a time.
To Support the same firmware allocates a DRAM region for each PF/VF for
storing LMTLINES. These LMTLINES are used to send CPT commands to HW.
PF/VF LMTST region is accessed via BAR4. PFs LMTST region is followed
by its VFs mbox memory. The size of region varies from 2KB to 256KB
based on number of LMTLINES configured.

This patch adds support for mapping of PF/VF LMTST region.

Mailbox region configuration has some changes on CN10K platform
from OcteonTX2(CN9XX) platform.

On CN10K platform:
The DRAM region allocated to PF is enumerated as PF BAR4 memory.
PF BAR4 contains AF-PF mbox region followed by its VFs mbox region.
AF-PF mbox region base address is configured at RVU_AF_PFX_BAR4_ADDR
PF-VF mailbox base address is configured at
RVU_PF(x)_VF_MBOX_ADDR = RVU_AF_PF()_BAR4_ADDR+64KB. PF access its
mbox region via BAR4, whereas VF accesses PF-VF DRAM mailboxes via
BAR2 indirect access.

On CN9XX platform:
Mailbox region in DRAM is divided into two parts AF-PF mbox region and
PF-VF mbox region i.e all PFs mbox region is contiguous similarly all
VFs.
The base address of the AF-PF mbox region is configured at
RVU_AF_PF_BAR4_ADDR.
AF-PF1 mbox address can be calculated as RVU_AF_PF_BAR4_ADDR * mbox
size.

This patch changes mbox initialization to support both CN9XX and CN10K
platform.
This patch also removes platform specific name from the PF/VF driver name
to make it appropriate for all supported platforms.

This makes the IXP4xx driver probe from the device tree
and retrieve the NPE and two queue manager handled used
to process crypto from the device tree.

As the crypto engine is topologically a part of the NPE
hardware, we augment the NPE driver to spawn the
crypto engine as a child.

The platform data probe path is going away in due time,
for now it is an isolated else clause.

The ixp4xx_crypto driver traditionally registers a bare platform
device without attaching it to a driver, and detects the hardware
at module init time by reading an SoC specific hardware register.

Change this to the conventional method of registering the platform
device from the platform code itself when the device is present,
turning the module_init/module_exit functions into probe/release
driver callbacks.

This enables compile-testing as well as potentially having ixp4xx
coexist with other ARMv5 platforms in the same kernel in the future.
