i3c: master: Support ACPI enumeration of child devices

Although the existing subsystem allows host controllers to register
through the ACPI table, it was not possible to describe I3C or I2C
devices when using ACPI. This is because the driver relied on the reg
property to retrieve the PID, static address, etc., whereas ACPI uses
_ADR or serial resources to describe such devices.

Read _ADR and LVR from ACPI resources and extract the data as per the
ACPI specification for an I3C bus. Also read mipi-i3c-static-address as
per the MIPI DISCO specifications [1] to get the static address to be
used.

Enable describing I3C or I2C devices in the ACPI table. This is required
if the device uses a static address or if it needs device-specific
properties.
