[PATCH v3 00/13] Support ACPI and SETAASA device discovery

[Akhil R <akhilrajeev@nvidia.com>]

This patch series adds SETAASA device discovery to the I3C subsystem,
enabling support for SPD5118 temperature sensors found on DDR5 memory
modules. The changes also add ACPI support for all existing DAA
methods like SETDASA, SETNEWDA as well as I2C devices on I3C bus.

SPD5118 and similar devices on DDR5 memory modules differ from typical
I3C devices in their initialization. They use SETAASA broadcast CCC
instead of ENTDAA for address assignment, and per JEDEC specification,
are not required to have a Provisioned ID or implement standard device
information CCC commands (GETPID, GETDCR, GETBCR).

The series enables to describe all I3C and I2C devices on both Device
Tree and the ACPI table, using unified device property APIs throughout
the I3C core and the Synopsys DesignWare I3C master driver.

Please note that the series modifies drivers across multiple subsystems,
like Device Tree bindings, ACPI, I3C and HWMON.

v2->v3:
  * Fix maximum value and indent bit list for mipi-i3c-static-method.
  * Move I3C_ADDR_METHOD_* macros to dt-bindings header.
  * Drop ACPICA commit IDs, keep only the Link: tags.
  * Revert the change which proceeds to register other devices if SETAASA
    is not supported so that it aligns with the rest of the driver and to
    avoid the issues pointed by Sashiko.
  * Rework multiple commit messages.

v1->v2:
  * Added patch to remove 16-bit addressing support for SPD5118
  * Guard ACPI calls with #ifdef CONFIG_ACPI
  * Remove CONFIG_OF guard for of_alias_get_highest_id()
  * Mask mipi-i3c-static-method in the driver to select only valid values.
  * Proceed to register other devices if SETAASA is not supported.
  * Update commit message and links in the description of multiple commits.
