This patch adds support for the GPIO found on the CP2105. Unlike the GPIO
provided by some of the other devices supported by the cp210x driver, the
GPIO on the CP2015 is muxed on pins otherwise used for serial control
lines. The GPIO have been configured in 2 separate banks as the choice to
configure the pins for GPIO is made separately for pins shared with each
of the 2 serial ports this device provides, though the choice is made for
all pins associated with that port in one go. The choice of whether to use
the pins for GPIO or serial is made by adding configuration to a one-time
programable PROM in the chip and can not be changed at runtime. The device
defaults to GPIO.
This device supports either push-pull or open-drain modes, it doesn't
provide an explicit input mode, though the state of the GPIO can be read
when used in open-drain mode. Like with pin use, the mode is configured in
the one-time programable PROM and can't be changed at runtime.

Add helper to access line-control register in order to work around a
cp2108 GET_LINE_CTL bug.
cp2108 GET_LINE_CTL returns the 16-bit value with the 2 bytes swapped.
However, SET_LINE_CTL functions properly. When the driver tries to modify
the register, it reads it, modifies some bits and writes back. Because the
read bytes were swapped, this often results in an invalid value to be
written. In turn, this causes cp2108 respond with a stall. The stall
sometimes doesn't clear properly and cp2108 starts responding to following
valid commands also with stalls, effectively failing.

This change is preparation for implementing a cp2108 bug workaround.
The workaround requires storing some private data. Right now the data is
attached to the USB interface and allocated in the attach() callback.
The bug detection requires USB I/O which is done easier from port_probe()
callback rather than attach(). Since the USB access functions take port
as a parameter, and since the private data is used exclusively by these
functions, it can be allocated in port_probe(). Also, all cp210x devices
have exactly 1 port per USB iterface, so moving private data from the USB
interface to port is trivial.

Flush all device queues at close in order to work around a cp2108 Tx
queue bug.
Occasionally, writing data and immediately closing the port makes cp2108
stop responding. The device has to be unplugged to clear the error.
The failure is induced by shutting down the device while its Tx queue
still has unsent data. This condition is avoided by issuing PURGE command
from the close() callback.
This change is applied to all cp210x devices. Clearing internal queues on
close is generally good.

Fixing typo for MeshConnect IDs. The original PID (0x8875) is not in
production and is not needed. Instead it has been changed to the
official production PID (0x8857).

Enable Silicon Labs Ember VID chips to enumerate with the cp210x usb serial
driver. EM358x devices operating with the Ember Z-Net 5.1.2 stack may now
connect to host PCs over a USB serial link.

This `usb_reset_device` command has been around since the driver was
originally reverse engineered. It doesn't cause much issue on single
interface CP210x devices, but on the CP2105 and CP2108 with 2 and 4
interfaces respectively it will cause instability on enumeration and
delays enumeration noticably. There should be no reason to reset a device
at startup, per the CP210x AN571 spec.

Corsair USB Dongles are shipped with Corsair AXi series PSUs.
These are cp210x serial usb devices, so make driver detect these.
I have a program, that can get information from these PSUs.
Tested with 2 different dongles shipped with Corsair AX860i and
AX1200i units.
