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.

We can thank Ilpo Järvinen for this V3! See below for changes compared
to V2.

Have a nice day,

Changes in v3:
- Replace magic constants in linux/amba/serial.h by FIELD_PREP_CONST calls
- Refactor QDF2400 SoC erratum 44 handling out of probe in a new patch
- A nit in "unindent pl011_console_get_options function body"
- Link to v2: https://lore.kernel.org/r/20231116-mbly-uart-v2-0-863f665ce520@bootlin.com

Changes in v2:
- [PATCH 2]: add #include <linux/bits.h> in include/linux/amba/serial.h
  as we use the BIT() macro.
- Move one whitespace cleanup from [PATCH 4/6] to [PATCH v2 3/5] where
  it belongs.
- Drop [PATCH 6/6]: console will never have a word length of 5 or 6.
- Link to v1: https://lore.kernel.org/r/20231026-mbly-uart-v1-0-9258eea297d3@bootlin.com
