The pl011 driver has gone back and forth on the definition of the
ZTE specific variation of the hardware definitions, but the
current state is that the vendor definition is left in place
yet unused:
drivers/tty/serial/amba-pl011.c:190:27: warning: 'vendor_zte' defined but not used [-Wunused-variable]
I don't know what the plan forward is to get this code to work,
but the current behavior is a bit annoying as we get a warning
whenever we build this driver.
This patch does not help us to make it work, but at least
shuts up the warning.

In all functions other than atmel_serial_probe_fifos,

refer to an instance of struct uart_port. In many of these functions,
"atmel_port" is used to refer to an instance of struct atmel_uart_port.
We make the use of the name "port" consistent by making
atmel_serial_probe_fifos, atmel_serial_probe, and atmel_console_init
use "atmel_port" to refer to an instance of struct atmel_uart_port
instead of the previous name of "port".

A driver property depends on the Atmel serial IP revision. This property
is the way the rx timeout is handled: by an hardware or software timer.
So, change this property name and setup code so that it's easier to understand

SoCs.

Properly initialize the struct console 'name' and 'index' fields for
the registering earlycon. For earlycons w/o trailing numerals, the
index is set to 0; otherwise, the index is set to the value of the
trailing numeral. For example, the 'exynos4210' earlycon name == "exynos"
and index == 4210. Earlycons with embedded numerals will have all
non-trailing numerals as part of the name; for example, the 's3c2412'
earlycon name == "s3c" and index == 2412.
This ackward scheme was initially added for the uart8250 earlycon;
adopt this scheme for the other earlycon "drivers".
Introduce earlycon_init() which performs the string scanning and
initializes the name and index fields; encapsulate the other console
field initializations within.

Use a single common table of struct earlycon_id for both command line
and devicetree. Re-define OF_EARLYCON_DECLARE() macro to instance a
unique earlycon declaration (the declaration is only guaranteed to be
unique within a compilation unit; separate compilation units must still
use unique earlycon names).
The semantics of OF_EARLYCON_DECLARE() is different; it declares an
earlycon which can matched either on the command line or by devicetree.
EARLYCON_DECLARE() is semantically unchanged; it declares an earlycon
which is matched by command line only. Remove redundant instances of
EARLYCON_DECLARE().
This enables all earlycons to properly initialize struct console
with the appropriate name and index, which improves diagnostics and
enables direct earlycon-to-console handoff.
