[PATCH] Revert "tty: serial: pl011: add ttyAMA for matching pl011 console"

[Mark Salter <msalter@redhat.com>]

This reverts commit aea9a80ba98a0c9b4de88850260e9fbdcc98360b.

It completely breaks PL011 SPCR support (a console=ttyAMA0 is
required to get a console even with a valid SPCR table).

Aleksey Makarov also noticed this:

  https://lkml.org/lkml/2017/3/1/324

and he is working on a more generalized patch to fix the original
"double printing" problem which this reverted patch was trying to
fix.

  https://lkml.org/lkml/2017/3/15/223

So, let's revert the broken patch and live with the double printing
until Aleksey's patch gets upstream.
