Syscall mount returns -ENODEV error if requested FS type
has not been found. Returning the same error from FFS mount
callback makes value returned to userspace misleading.

Other file systems returns -ENOENT if requested device
has not been found. Adjust FFS to this convention to make
error codes meaningfull.

This patch adds support for the PLX USB3380 and USB3382.

This driver is based on the driver from the manufacturer.

Since USB338X is register compatible with NET2280, I thought that it
would be better to include this hardware into net2280 driver.

Manufacturer's driver only supported the USB33X, did not follow the
Kernel Style and contain some trivial errors. This patch has tried to
address this issues.

This patch has only been tested on USB338x hardware, but the merge has
been done trying to not affect the behaviour of NET2280.

Newer DWC3 controllers can be built for USB 2.0-only mode, where
most of the USB 3.0 circuitry is left out. To support this mode,
the driver must limit the speed programmed into the DCFG register
to Hi-Speed or lower.

Reads and writes to the PIPECTL register are left as-is, since
they should be no-ops in USB 2.0-only mode. Calls to phy_init()
etc. for the USB3 phy are also left as-is, since the no-op USB3
phy should be used for USB 2.0-only mode controllers.

The various devm_ functions allocate memory that is released when a
driver detaches.  This patch uses devm_kzalloc, devm_request_irq,
devm_gpio_request, devm_regulator_get etc. for data that is
allocated in the probe function of a platform device and is only
freed in the remove function. The corresponding free functions are
removed and the labels are done away with.
