drivers: caam: implement CAAM DMA Object

Implementation of a CAAM DMA object to:
- create a DMA object (SGT/buffer) based on input/output buffers
- reallocate a new buffer accessible from the CAAM address space
- ensure buffer is cache aligned (for the output)

Implementation of CAAM DMA object functions to:
- cache maintenance
- free CAAM DMA object

drivers: caam: Modify access of 64 bit registers

The Address of Input/output Job ring and scatter gather table are
handled differently depending on platform

1. All BE CAAM platforms (LS1043, LS1012, LS1046)
and i.MX platforms (LE CAAM):
base + 0x0000 : most-significant 32 bits
base + 0x0004 : least-significant 32 bits

The 32-bit version of this core therefore has to write to base + 0x0004
to set the 32-bit wide DMA address.

2. All other LE CAAM platforms (LS2088, LS1088, LX2160 etc.)
base + 0x0000 : least-significant 32 bits
base + 0x0004 : most-significant 32 bits

drivers: CAAM driver User Buffer SGT create

CAAM Driver can operate directly with the User Buffer and in this
case, the buffer can be on non-contiguous physical page.

CAAM is using a DMA to load/store data from memory. The DMA is working
with physical address. In case of the User Buffer, if the buffer is
crossing multiple Small Page, a CAAM Scatter Gather Table needs to
be created to rebuild the physical memory chunks used by the User virtual
buffer.

Add a function to check if a buffer is a User buffer crossing mutliple
small page.
Add a function to create a SGT Table of the User buffer.
