Precedence: bulk

Hi,

While adding upstream support to a new platform (Mobileye EyeQ5[1]) that
uses the AMBA PL011 driver, I took some time to look at the PL011
driver and ended up with a few patches that cleanup parts of it. The
line-diff is big mostly because of the checkpatch-fixing commits.

The driver hadn't received any love for quite some time. See commit
messages for more information.

v5 has been rebased upon v6.7-rc1, with [PATCH v4 3/6] split into many
small commits and a header include in [PATCH v4 2/6] to fix a kernel
test robot report.

Have a nice day,
Théo Lebrun
