Pull request overview
This PR updates the NXP i.MXRT BSP (focused on RT1180 EVK) to add/enable RT1180-specific peripheral features (DMA routing, new RTC implementation, SDIO cache maintenance, etc.) and to align board configs/Kconfig/CI attach configs with the new capabilities.
本 PR 更新了 NXP i.MXRT BSP（主要面向 RT1180 EVK），新增/使能 RT1180 相关外设能力（DMA 路由、新 RTC 实现、SDIO Cache 维护等），并同步更新板级配置、Kconfig 与 CI 附加配置。
Changes / 变更：
- Add RT1180-specific DMA request mux/base handling for LPUART and LPSPI; adjust SPI init/export stage.
为 LPUART/LPSPI 增加 RT1180 专用 DMA request mux/base 处理；调整 SPI 初始化/导出阶段。 - Add a new BBNSM-based RTC driver for RT1180 and a generic DWT cycle-counter utility driver.
为 RT1180 新增基于 BBNSM 的 RTC 驱动，并新增通用 DWT 周期计数/延时工具驱动。 - Update SDIO driver (RT1180 cache maintenance), board pinmux, Kconfig/.config, CI attachconfig, and BSP READMEs to reflect supported peripherals.
更新 SDIO 驱动（RT1180 Cache 维护）、板级 pinmux、Kconfig/.config、CI attachconfig 与 BSP README 外设支持状态。

- Title: current prefix is uppercase (
[BSP][NXP]). Repo convention expects lowercase prefix; consider something like:
English:[nxp][imxrt] Add RT1180 I2C/SPI/CAN/SDIO/DWT + BBNSM RTC
中文：当前标题前缀为大写（[BSP][NXP]），建议按仓库惯例改为小写前缀，例如：[nxp][imxrt] ... - Description: still contains the template bracket wrapper and the “action” link is empty; please clean it up and add the CI/action link if required.
中文：描述里仍保留了模板方括号包裹内容，且 action 链接为空；建议清理并补充验证/CI 链接。

- [bug/错误]: Persisted epoch is truncated to 32-bit when saving to BBNSM GPR
English: bbnsm_gpr_save() writes BBNSM->GPR[GPR_IDX_EPOCH] = (uint32_t)epoch;, which drops the upper bits of epoch on 64-bit time_t builds. This breaks SET_TIME/GET_TIME correctness once the upper bits are non-zero. Please store epoch as a 64-bit value split across two GPR registers.
中文：bbnsm_gpr_save() 里 BBNSM->GPR[...] = (uint32_t)epoch; 会在 time_t 为 64 位时丢失高 32 位，导致 SET_TIME/GET_TIME 在高位非 0 时计算错误。建议将 epoch 作为 64 位值拆分到两个 GPR 寄存器保存。
bsp/nxp/imx/imxrt/libraries/drivers/drv_rtc_bbnsm.c:152
- [bug/错误]: Restoring epoch reads only one 32-bit GPR slot
English: bbnsm_gpr_restore() reconstructs *out_epoch from a single GPR word. After saving epoch as a 64-bit split value, restore must reconstruct from high/low words to keep GET_TIME correct across warm resets.
中文：bbnsm_gpr_restore() 目前仅从一个 32 位 GPR 恢复 *out_epoch。如果按建议将 epoch 拆分为 64 位存储，这里也需要从高/低 32 位重建，才能保证 warm reset 后 GET_TIME 正确。
