Patch Review

**Purpose**: Replace `udelay(1)` with `fsleep(1000)` — increasing from 1 usec to 1 msec per the hardware manual requirement of >= 1 msec after CMN_RSTB deassertion.

**Review**:

This is a straightforward and clearly correct fix. The original `udelay(1)` was three orders of magnitude too short per the hardware manual.

1. **Use of `fsleep(1000)` is appropriate**: `fsleep()` automatically selects between `udelay`, `usleep_range`, and `msleep` based on the duration. For 1000 usec, it will use `usleep_range()`, which is correct for a non-atomic context (this is called from the bridge enable path, which can sleep).

2. The Fixes tag and stable Cc are appropriate — this was a real hardware requirement being violated.

**Verdict**: Clean one-liner fix. No issues.
