1. 请补充commit message并添加自己的signed-off
2. CONFIG_FW_LOADER_COMPRESS_XZ也启用下，不然xz压缩的固件还是不能用吧

Pull Request Overview

This PR enables Zstandard (zstd) compression support for the firmware loader in the Deepin RISC-V64 desktop defconfig.

• Add CONFIG_FW_LOADER_COMPRESS_ZSTD to enable zstd decompression in the firmware loader.
• Ensures that zstd support is built alongside existing firmware compression mechanisms.

• [nitpick] Consider updating the relevant Kconfig help text or driver documentation to mention that zstd support is now available for firmware loading.

CONFIG_FW_LOADER_COMPRESS_ZSTD=y

在提供的代码更改中，添加了两个新的配置选项 CONFIG_FW_LOADER_COMPRESS_XZ 和 CONFIG_FW_LOADER_COMPRESS_ZSTD。这些配置选项用于启用对固件加载器（FW_LOADER）的 XZ 和 ZSTD 压缩支持。以下是针对这个更改的一些建议：

代码质量

1. 配置文件格式：确保配置文件中的新选项格式正确，并且与现有配置项保持一致。
2. 注释说明：在添加新配置项时，应该添加相应的注释说明，解释为什么需要启用这些压缩选项，以及它们可能带来的好处。

代码性能

1. 压缩算法选择：确认选择 XZ 和 ZSTD 压缩算法是基于性能需求还是存储空间需求。如果是为了优化性能，应该进行基准测试，确保选择的是最适合当前系统的算法。

代码安全

1. 固件安全性：启用压缩功能可能会增加固件加载过程中的安全风险，因为压缩文件可能更容易受到攻击。确保固件加载过程是安全的，并且压缩算法本身是安全的。

其他建议

1. 配置项的依赖性：确认这些配置项是否依赖于其他配置项。如果它们依赖于特定的内核版本或硬件特性，应该添加相应的依赖性检查。
2. 文档更新：如果这些更改会影响用户或开发者，应该更新相应的文档，说明如何启用和配置这些新选项。

总体来说，这个更改看起来是为了提高固件加载的性能和效率，但需要确保相关的安全性和性能测试都已经到位。
