Summary

Sync xhci_salina.patch with the cleaned Salina xHCI/Bluetooth patch currently carried by bizkut/ps5-linux-patches.

This keeps the standalone driver patch useful as a source/reference patch for the PS5 Salina xHCI path while matching the integrated kernel patch used by the PS5 Linux build.

What changed

Replaces the older pseudo-C/debug-heavy patch with a cleaned GPL-2 kernel patch.
Adds the PS5 Salina xHCI glue/PHY driver.
Maps PCI BARs dynamically instead of relying on hard-coded mappings.
Defers Salina PHY init until SPCIE is initialized, and retries when PHY init times out.
Adds Salina reset and event-poller lifecycle hooks.
Exposes xhci_handle_events() through xhci-ring.h.
Adds a bounded Salina event-ring stuck guard.
Adds the explicit PS5 Salina xHCI PCI ID.
Raises the xHCI RExit timeout for PS5 timing behavior.
Adds IW620 Bluetooth quirks used by the PS5 internal Bluetooth path.

Provenance

The final standalone patch was derived from the kernel patch delta between upstream ps5-linux/ps5-linux-patches and bizkut/ps5-linux-patches bluetooth-fix.

The resulting xhci_salina.patch matches the appended Salina/Bluetooth section of linux.patch byte-for-byte.

Validation

Confirmed the fork branch is clean before opening the PR.
Confirmed the final standalone patch byte-for-byte matches the Salina/Bluetooth section extracted from linux.patch.
The same patch is used by the PS5 Linux kernel build flow.

I did not run git apply --check here because this local workspace does not contain a clean Linux kernel checkout.
