[ Upstream commit e8b9fc10f2 ]
if of_find_device_by_node() succeed, dwc3_octeon_device_init() doesn't have
a corresponding put_device(). Thus add put_device() to fix the exception
handling for this function implementation.

There's an intentional switch case fall-through in Cavium Octeon USB
code, which triggers compile errors with -Wimplicit-fallthrough due to
-Werror being enabled for arch/mips.
This can be encountered when building cavium_octeon_defconfig.
Fix the build issue by annotating the intentional fall-through.

cvmx_gpio_bit_cfgx bitfields are indentical on cn70xx and cn73xx,
and also match the default definition. So use that instead.

Add all the necessary platform code to initialize the dwc3
USB host controller. This code initializes the clocks and
performs a reset on the USB core and PHYs. The driver code
in 'drivers/usb/dwc3' is where the real driver lives.
