Why return Box<dyn Error> as error type?
Maybe you just return a string? Can we return AxError?

OnProbeError uses Box<dyn Error>, these two error type are in other crates, if we want to use ? to convert err, need to create new type to warp a String or AxError，and boxed error has more err msg than AxError, make it easier to find error location.

[fix] 优化错误处理格式，简化 MMIO 区域映射失败的错误信息 feat(axdriver): update rdrive dependency and add block driver support - Updated rdrive dependency version from 0.14 to 0.14.4 in Cargo.toml. - Introduced a new block driver module with implementations for block operations. - Added virtio block driver support with MMIO transport. - Refactored interrupt controller (GIC) driver probes to use OnProbeError for error handling. - Enhanced dynamic driver probing to include block devices when the "block" feature is enabled. - Improved error handling in block driver operations by mapping errors between driver and I/O layers.
