config: 基于 linux-6.6.143 清理并标准化内核默认配置

[sterling-teng]

基于上游 linux-6.6.y 最新稳定版本，规整 RVCK 内核配置，清理冗余的下游板级定制配置，优化代码库碎片化问题。

RVCK 是面向 RISC-V 架构的同源统一内核项目，核心目标是整合各厂商的下游内核代码、解决跨板级代码冲突，实现单套代码统一适配、启动所有硬件板卡。此前项目长期占用上游原生通用 defconfig，同时累积了大量冗余的板级BSP专用配置，不仅存在遗漏上游修复补丁的风险，也持续导致代码库碎片化，不利于长期维护与上游同步。

该补丁集共包含三项递进式优化改动：

1. 复制现有通用默认配置，独立创建 rvck_defconfig 专属配置文件，不再占用上游 linux-6.6.y 原生 defconfig，规避同步过程中遗漏上游修复补丁的风险。
2. 清理大量冗余、过剩的板级BSP专属配置，遏制代码库持续碎片化问题，保障RVCK同源统一内核的代码一致性。
3. 完整还原所有内核配置，对齐上游最新稳定标签 linux-6.6.143，实现配置基线与上游内核标准完全统一。

本次所有补丁无任何功能变更。所有改动仅优化配置管理方式、统一上游配置基线，彻底解决配置碎片化问题，为后续RVCK项目持续同步上游代码、迭代维护奠定标准化基础。

fixed #251

有个疑问：恢复上游的 defconfig 后，我发现直接拿这个配置编译 rvck 内核会失败，报错:

arch/riscv/mm/init.c:187:2: error: #error Please unset CONFIG_DEBUG_VM when CONFIG_HIGHMEM is set, because CONFIG_DEBUG_VM will trigger VM_BUG_ON_PAGE in __free_pages()->put_page_testzero().

make[6]: *** [scripts/Makefile.build:243: arch/riscv/mm/init.o] Error 1
make[6]: *** Waiting for unfinished jobs....

我尝试参考 rvck_defconfig 关闭了 CONFIG_HIGHMEM， 可以编译成功，但是拿这个内核去启动 QEMU 上的 openEuler 启动会失败(以前基于 rvck-6.6 分支的 defconfig 是可以启动)。

请问以后怎么对待 defconfig 这个文件，我们需要让 rvck 支持它么？

另外还有一个问题，就是这个 PR 的改动对 ci 是有影响的吧？ 原先 ci 用的是 defconfig 吧？如果 ci 有影响并且需要修改这个 rvck 仓库，我建议需要在本 PR 中一起解决掉（单独一个 commit）。
