Claude review: drm: renesas: rzg2l_mipi_dsi: Increase reset deassertion delay to 1 msec

[Claude Code Review Bot <claude-review@example.com>]

Patch Review

Changes the delay after CMN_RSTB deassert from `udelay(1)` (1 usec) to `fsleep(1000)` (1 msec), matching the hardware manual's >= 1 msec requirement.

```c
-		udelay(1);
+		fsleep(1000);
```

This is a clear fix — `udelay(1)` is 1 microsecond, three orders of magnitude less than the required 1 millisecond. Using `fsleep()` is the correct API choice here: for a 1ms delay, `fsleep` will use `usleep_range()` internally, which is appropriate for non-atomic context (this runs from `atomic_pre_enable` bridge callback, which is a process context despite the "atomic" name).

**Missing Fixes tag:** This patch fixes a real hardware timing violation (1 usec vs required 1 msec) and could reasonably carry a `Fixes:` tag pointing to the original commit that introduced the `udelay(1)`. If the driver has been working despite this, it may be that the hardware is tolerant, but it's still out of spec.
