Subject: [PATCH 5.11 092/254] ARM: dts: at91: sam9x60: fix mux-mask to match products datasheet

From: Nicolas Ferre <nicolas.ferre@...rochip.com>

commit 2c69c8a1736eace8de491d480e6e577a27c2087c upstream.

Fix the whole mux-mask table according to datasheet for the sam9x60
product.  Too much functions for pins were disabled leading to
misunderstandings when enabling more peripherals or taking this table
as an example for another board.
Take advantage of this fix to move the mux-mask in the SoC file where it
belongs and use lower case letters for hex numbers like everywhere in
the file.
