Subject: [PATCH 5.10 420/452] ARM: pxa: maybe fix gpio lookup tables

From: Arnd Bergmann <arnd@...db.de>

commit 2672a4bff6c03a20d5ae460a091f67ee782c3eff upstream.

>>From inspection I found a couple of GPIO lookups that are
listed with device "gpio-pxa", but actually have a number
from a different gpio controller.

Try to rectify that here, with a guess of what the actual
device name is.
