The acpi_handle should be just a handle and not a pointer in
sdw_intel_acpi_scan() parameter list.
It is called with 'acpi_handle handle' as parameter and it is passing it to
acpi_walk_namespace, which also expects acpi_handle and not  acpi_handle*

This structure is used to copy information from the 'sdw_slave'
structures, it's better to create a flexible array of 'sdw_slave'
pointers and directly access the information. This will also help
access additional information stored in the 'sdw_slave' structure,
such as an SDCA context.

This patch does not add new functionality, it only modified how the
information is retrieved.

Intel platforms have enabled 4 links since the beginning, newer
platforms now have 5 links. Update the definition accordingly.

This patch will have no effect on older platforms where the number of
links was hard-coded. A follow-up patch will add a dynamic check that
the ACPI-reported information is aligned with hardware capabilities on
newer platforms.

In older platforms, the number of links was constant and hard-coded to
4. Newer platforms can have varying number of links, so we need to add
a probe-time check to make sure the ACPI-reported information with
_DSD properties is aligned with hardware capabilities reported in the
SoundWire LCAP register.

The ACE3 IP used in PantherLake exposes new bitfields in the ACTMCTL
register to better control clocks/delays. These bitfields were
reserved/zero in the ACE2.x IP, to simplify the integration the new
bifields are added unconditionally. The behavior will only be impacted
when the firmware exposes DSD properties to set non-zero values.
