Subject: [PATCH v4 07/11] tty: 8250: Fix up PX-803/PX-857

The PX-803/PX-857 are variants of each other, add a note.
Additionally fix up the port counts for the card (2, not 1).

Fixes: ef5a03a26c87 ("tty: 8250: Add support for Brainboxes PX cards.")
Cc: stable@...r.kernel.org
Signed-off-by: Cameron Williams <cang1@...e.co.uk>
---
For stable: This patch is only applicable to 5.15 LTS and up, other LTS
kernels dont have PX card support.

v3 - v4:
Split patch v3 part 5 into multiple Fixes patches and an Additions patch.
Add Fixes: and Cc: tag.

v2 - v3:
Alter commit message a little to make the additions/fixes cleaner
Re-submit patch series using git send-email to make threading work.

v1 - v2:
This is a resubmission series for the patch series below. That series
was lots of changes sent to lots of maintainers, this series is just for
the tty/serial/8250 subsystem.
