Previously, the driver would always reconfigure the PSE hardware on
probe, causing a port matrix reflash that resulted in temporary power
loss to all connected devices. This change maintains power continuity
by preserving existing configuration when the PSE has been previously
initialized.

## Form letter - net-next-closed

The merge window for v6.18 has begun and therefore net-next is closed
for new drivers, features, code refactoring and optimizations. We are
currently accepting bug fixes only.

Please repost when net-next reopens after October 12th.

RFC patches sent for review only are obviously welcome at any time.

Oops sorry that is totally true and I forgot that we have entered the merge
window. Sorry for the noise :/
