Cleaning up redefinition of mpm areas and moving to use what is defined
in the base device tree files as is.
This effectively changes to a new memory partition.
Note that this change needs a corresponding change in the dts files in
the kernel tree to adjust the mpm memory area to the new memory
partition.
The CMEM areas here are adjusted such that there is no overlap with the
mpm areas defined in the dts files in the kernel tree.
Note also the address ranges are arranged differently for K2G compared
to the other Keystone platforms.
(This is to accomodate common memory map for multiple k2g platforms)

Also fixes issue with K2L, by removing overlapping memory area section.

cmem.dtsi splits the already defined dsp_common_mpm_area DDR memory into
a smaller MPM segment and other CMEM blocks.
The mpm_block_mem is removed and instead the original memory sections
dsp_common_mpm_area and mpm_mem in the kernel dtb are updated to reflect
On the MSMC memory, cmem.dtsi defines a sram subnode instead of the
reserved memory.
mpm MSMC areas are already captured in the kernel dtb.

This new device tree file is to support pruss with uio based drivers
alone.
Adds uio entries for pruss susbsystem and disables other drivers
controlling the same.
New dtb is added only if ENABLE_TI_UIO_DEVICES is enabled.

To reserve contiguous memory for CMEM:
* include the "recipes-kernel/linux/cmem.inc"
* Set CMEM_BASE and CMEM_SIZE to the physical memory address and size,
respectively, to reserve for CMEM.
Currently limited to reserving a single memory region used to create
a single buffer pool of a single buffer.
