dechao_gong f156812c0c arch/arm: add Realtek AmebaSmart (RTL8730E) CA32 support 
Add NuttX support for the Realtek AmebaSmart (RTL8730E) running on the
CA32 (Cortex-A32) application core, with the KM4/KM0 cores kept as
vendor firmware (KM4 acts as the WiFi network processor over WHC IPC).

Stage 1 bring-up, hardware verified:

  - CA32 boot / exception vectors / MMU + page allocator / heap
  - LOGUART console (RX via KM0-owned IPC + shared memory)
  - IRQ controller, timer, serial
  - On-chip SPI NOR flash MTD -> littlefs mounted at /data
  - WHC-host WiFi netdev (STA): scan / connect / DHCP, verified end to
    end (association -> 4-way -> DHCP -> ping, bidirectional TCP)

IC-agnostic Ameba glue is shared from arch/arm/src/common/ameba via a
relative VPATH entry (matching the rtl8721dx pattern), which also avoids
the empty mkdeps --dep-path that a leading-":" VPATH entry produced and
which intermittently broke parallel .ddc dependency generation.

The FIP packaging / flash image assembly is driven by
common/ameba/tools/ameba_smart_flash.sh from the board scripts.

Vendor blobs and build artefacts under the board prebuilt/ directory are
kept out of the tree via prebuilt/.gitignore.
