Subject: [PATCH] tty: serial: bcm63xx: use more precise Kconfig symbol

From: Rafał Miłecki <[email-masked]>
Date: Fri, 11 Mar 2022 10:32:33 +0100

Patches lowering SERIAL_BCM63XX dependencies led to a discussion and
documentation change regarding "depends" usage. Adjust Kconfig entry to
match current guidelines. Make this symbol available for relevant
architectures only.
