[PATCH v9 0/7] nfc: pn533: add uart phy driver

The purpose of this patch series is to add a uart phy driver to the
pn533 nfc driver.
It first changes the dt strings and docs. The dt compatible strings
need to change, because I would add "pn532-uart" to the already
existing "pn533-i2c" one. These two are now unified into just
"pn532". Then the neccessary changes to the pn533 core driver are
made. Then the uart phy is added.
As the pn532 chip supports a autopoll, I wanted to use this instead
of the software poll loop in the pn533 core driver. It is added and
activated by the last to patches.
The way to add the autopoll later in seperate patches is chosen, to
show, that the uart phy driver can also work with the software poll
loop, if someone needs that for some reason.
This patchset is already rebased on Johans "NFC: pn533: fix
use-after-free and memleaks" patch
https://lore.kernel.org/netdev/20191007164059.5927-1-johan@kernel.org/
as they would conflict.
If for some reason Johans patch will not get merged, I can of course
provide the patchset without depending on this patch.
