[PATCH 0/2] drm/tyr: add Job IRQ handling and GPU event wait support

[Laura Nao]

This series follows up to [1], which adds support for firmware loading
and MCU booting to the Tyr driver. The changes included here were
originally introduced in v4[2], then dropped to reduce the scope of the
series, and have been adjusted to work with the HRT (Higher-Ranked
Lifetime Types) driver architecture recently introduced.

The first commit adds a new Wait type, wrapping a CondVar and a Mutex,
for sleeping until a condition is met or a timeout expires. This can be
used to wait for GPU-driven events.

The second commit adds a threaded IRQ wrapper for the firmware Job
interrupts, used to signal events from the global CSF (GLB) and Command
Stream Group (CSG) interfaces.

These changes will be later used to wait for global CSF interface
readiness after firmware boot, as part of the CSF firmware interfaces
support that will be submitted as a separate series.

This series is based on drm-rust-next and depends on:
- [PATCH v7 0/7] drm/tyr: firmware loading and MCU boot support[1]
- [PATCH v2] rust: irq: make Registration compatible with lifetime-bound drivers[2]
