PHY_CLK_VALID bit doesn't work properly with UTMI PHY.
e.g. This bit is always zero on P5040, etc.
There is no need to check this bit for UTMI PHY, just keep
checking for ULPI PHY to prevent system hanging.
This patch should be squashed into previous commit 3735ba8db8

It's out-dated for the tty-layer stuff, and would require a bunch of
work. That's not really a big deal, the big issue is that there is no
company contact for the hardware, so questions we have about it (like
why isn't this just handled by the cdc-acm driver instead?) go
unanswered.
So drop the driver. If someone comes along to help answer the
questions, we can easily revert this and fix up the code.

The three Pantech devices UML190 (106c:3716), UML290 (106c:3718) and
P4200 (106c:3721) all use the same subclasses to identify vendor
specific functions. Replace the existing device specific entries
with generic vendor matching, adding support for the P4200.

This patch (as1606) converts two warning messages in the ehci-hcd
driver to debug messages, and adds a little extra information to each.
The log messages occur when an EHCI controller takes too long (more
than 20 ms) to turn its async or periodic schedule on or off. If this
happens at all, it's liable to happen quite often and there's no point
spamming the system log with these warnings. Furthermore, there's
nothing much we can do about it when the problem happens.

This patch (as1605) removes a useless test from the EHCI debugfs
code. There's no point checking whether p.qh is non-NULL; we already
know it is and in any case it gets dereferenced aerlier in the
function.
The useless test was identified by smatch.

This patch adds new functions to upload firmware to the controller. The
drivers currently using ezusb are adapted to use these new functions.
This also fixes a bug occuring during firmware loading in the
whiteheat-driver:
The driver iterates over an ihex-formatted firmware using ++ on a "const
struct ihex_binrec*" which leads to faulty results, because ihex data is
read as length. The function "ihex_next_binrec(record)" has so be used
to work correctly

Just like for the in-tree early console debug port driver, the
hypervisor - when using a debug port based console - also needs to be
told about controller resets, so it can suppress using and then
re-initialize the debug port accordingly.
Other than the in-tree driver, the hypervisor driver actually cares
about doing this only for the device where the debug is port actually
in use, i.e. it needs to be told the coordinates of the device being
reset (quite obviously, leveraging the addition done for that would
likely benefit the in-tree driver too).

This moves to using pr_info() where needed instead of a "raw" printk()
call, making the whole driver more unified.

The driver was calling printk() directly at startup, which is just
noise. Switch over to using pr_info() where needed, and get rid of the
totally useless version number that had never ever been incremented.

These somehow got missed previously (as they weren't calling dbg(), but
rather printk() directly), so move over to using dev_dbg() as we never
want to see startup messages unless debugging is enabled.

No one needs to know that the driver is loaded (almost all other USB
serial drivers are now quiet), so just load quietly.
Also remove unused, and unneeded version information from the driver,
that was pointless.
