Subject: [PATCH v3 3/3] drm/appletbdrm: use %p4cl instead of %p4cc

From: Aditya Garg <gargaditya08@...e.com>

Due to lack of a proper printk format, %p4cc was being used instead of
%p4cl for the purpose of printing FourCCs. But the disadvange was that
they were being printed in a reverse order. %p4cl should correct this
issue.
