[dinesh.maniyam at altera.com]

From: Dinesh Maniyam <dinesh.maniyam at altera.com>

This patchset add Synopsys MIPI I3C Driver support for
Intel Agilex5 devices.

The i3c driver is leveraged from the master/dw-i3c-master.c,
i3c/device.c and i3c/master.c Linux version 6.6.37 LTS
And few header files included to be
part of the migration; i3c/internals.h, include/linux/i3c/ccc.h,
include/linux/i3c/device.h and include/linux/i3c/master.h.
Additional i3c uclass driver and command files added to support
i3c read and write in U-Boot.

Patch status:

Detail changelog can find in commit message.

v5->v4:
--------
- Add header file to doc/api/i3c
- Rephrase function description for i3c.h 
- Separated subcommand as a function for cmd/i3c.c
- Used memory address to transfer msgs from i3c
- Rephrase description in cmd/i3c.rst file
- Replaced int with unsigned for positive variables.

v4->v3:
--------
Resolve ci test:
- Add i3c node in index.rst
- Formating error in i3c.rst
- Resolve cpu_relax undefined for sandbox

v3->v2:
--------
- Squash commit 10 to commit 9
- Resolve index for new files to pass the checkpatch
