Subject: [PATCH v2] scripts: generate_rust_analyzer: fix resolution of
 #[pin_data] macros

From: SeungJong Ha <engineer.jjhama@...il.com>

Currently, rust-analyzer fails to properly resolve structs annotated with
`#[pin_data]`. This prevents IDE features like "Go to Definition" from
working correctly for those structs.

Add the missing configuration to `generate_rust_analyzer.py` to ensure
the `pin-init` crate macros are handled correctly.

I encountered an issue where rust-analyzer fails to analyze
structs decorated with the #[pin_data] attribute while testing
Rust kernel modules.

It appears that the dependencies for pin-init and drivers were
missing from the analyzer's configuration. This patch adds
those missing dependencies.

I have verified that my rust-analyzer correctly processes
\#[pin_data] structs after applying this fix.

Best regards, SeungJong

Changes in v2:
- Fix typos
- Drop the quote module workaround (will be handled separately)
- Rebase onto `rust-fixes`
- Add `pin_init` dependency for Rust drivers
- Link to v1: https://lore.kernel.org/r/20260123-fix-pin-init-crate-dependecies-v1-1-1c6cfe9aa352@gmail.com
