Pull request overview

This PR updates the zynqmp-a53-dfzu2eg BSP toward a “full DM” (device model) configuration by switching to OFW/FDT-based hardware description and adding DM-style UART/RTC drivers for ZynqMP, along with the build/config changes needed to support the new flow.

Changes:

• Add a ZynqMP device tree (zynqmp.dts) and build it into a DTB during BSP build.
• Enable DM/OFW/builtin-FDT in BSP config and hook up new DM drivers (Cadence/Xilinx UARTPS + ZynqMP RTC).
• Remove legacy non-DM BSP driver headers/implementations and simplify board init to rt_hw_common_setup().

bsp/zynqmp-a53-dfzu2eg/Kconfig:24

• [bug/类别: bug]: BSP-local driver Kconfig files are not sourced

English: This BSP adds drivers/serial/Kconfig and drivers/rtc/Kconfig, but the top-level BSP Kconfig does not source/rsource them (and the old source "$(BSP_DIR)/drivers/Kconfig" was removed). As a result, symbols like RT_SERIAL_XILINX_PS / RT_RTC_ZYNQMP may be undefined in menuconfig and .config loading can break.
中文：该 BSP 新增了 drivers/serial/Kconfig 和 drivers/rtc/Kconfig，但 BSP 顶层 Kconfig 没有通过 source/rsource 引入它们（且原来的 source "$(BSP_DIR)/drivers/Kconfig" 已被移除）。这样会导致 RT_SERIAL_XILINX_PS / RT_RTC_ZYNQMP 等符号在 menuconfig 中未定义，读取/生成 .config 可能失败。

SOC_DM_RTC_DIR      := $(BSP_DIR)/drivers/rtc
SOC_DM_SERIAL_DIR   := $(BSP_DIR)/drivers/serial

source "$(RTT_DIR)/Kconfig"
osource "$PKGS_DIR/Kconfig"

config SOC_ZYNQMP_AARCH64
    bool
    select ARCH_ARMV8
    select RT_USING_COMPONENTS_INIT
    select RT_USING_USER_MAIN
    select ARCH_CPU_64BIT
    select RT_USING_CACHE
