Subject: [PATCH 0/7] Refactor sa8775p/qcs9100 to common names lemans-auto/lemans

This patch series refactors the sa8775p and qcs9100 platforms and introduces
a unified naming convention for current and future platforms (qcs9075).

The motivation behind this change is to group similar platforms under a
consistent naming scheme and to avoid using numeric identifiers.
For example, qcs9100 and qcs9075 differ only in safety features provided by
the Safety-Island (SAIL) subsystem but safety features are currently
unsupported, so both can be categorized as the same chip today.

Since, most of our platforms are IoT-based so "lemans" can be served as the
default IoT variant, with "lemans-auto" derived from it. Accordingly:
  - qcs9100/qcs9075 and its associated IoT platforms are renamed to lemans
    which needs different memory-map. So, latest memory-map is updated
    here as per IOT requirements.
  - sa8775p and its associated platforms are renamed to "lemans-auto", which
    is derived from "lemans", that retains the old automotive memory map to
    support legacy use cases.
  - Both lemans & lemans-auto are serving as non-safe chip and if needed
    additional dtsi can be appended in the future to enable safety features.

Additionally:
  - Refactor common daughter cards used in Ride/Ride-R3 platforms into a
    common configuration. Also, introduce new files for different ethernet
    capabilities in Ride/Ride-r3. Since Ethernet functionality in Ride/Ride-r3
    is currently broken upstream, this patch focuses only on refactoring.
  - Include support for qcs9075 EVK[1] platform as lemans-evk. Currently,
    basic features are enabled supporting 'boot to shell'.
  - Remove support for qcs9100-ride, as no platform currently exists for it.

Funtional impact to current boards with refactoring:
  - No functional change on auto boards i.e sa8775p ride/ride-r3 boards
    (renamed as lemans-auto ride/ride-r3), and it is verified by comparing
    decompiled DTB (dtx_diff).
  - qcs9100 ride-r3 (renamed as lemans-ride-r3) is having new memory-map
    and rest other functionalities are still same.
