[PATCH 13/13] drivers/watchdog: use USB API functions rather than constants

This set of patches introduces calls to the following set of functions:

usb_endpoint_dir_in(epd)
usb_endpoint_dir_out(epd)
usb_endpoint_is_bulk_in(epd)
usb_endpoint_is_bulk_out(epd)
usb_endpoint_is_int_in(epd)
usb_endpoint_is_int_out(epd)
usb_endpoint_num(epd)
usb_endpoint_type(epd)
usb_endpoint_xfer_bulk(epd)
usb_endpoint_xfer_control(epd)
usb_endpoint_xfer_int(epd)
usb_endpoint_xfer_isoc(epd)

In some cases, introducing one of these functions is not possible, and it
just replaces an explicit integer value by one of the following constants:

USB_ENDPOINT_XFER_BULK
USB_ENDPOINT_XFER_CONTROL
USB_ENDPOINT_XFER_INT
USB_ENDPOINT_XFER_ISOC

An extract of the semantic patch that makes these changes is as follows:

[WATCHDOG] orion5x_wdt: fix compile issue by providing tclk as platform data

The orion5x-wdt driver is now registered as a platform device and
receives the tclk value as platform data. This fixes a compile issue
cause by a previously removed define "ORION5X_TCLK".

[WATCHDOG] rc32434_wdt: add timeout module parameter

The WDT timer ticks quite fast (half of the CPU clock speed, which may
be between 198MHz and 330MHz (or 400MHz on newer boards)). Given it's
size of 32Bit, the maximum timeout value ranges from about 21s to 43s,
depending on the configured CPU clock speed.

This patch add's the timeout module parameter and checks that it's not
bigger then the maximum timeout for the given clock speed.

[WATCHDOG] w83697ug: add error checking

I noticed the W83697UG driver tries to register a watchdog even though
it already noticed the chip isn't there.

WDT driver for the Winbond(TM) W83697UG/UF Super I/O chip initialising.
w83697ug/uf WDT: No W83697UG/UF could be found
w83697ug/uf WDT: Watchdog already running. Resetting timeout to 60 sec
w83697ug/uf WDT: cannot register miscdev on minor=130 (err=-16)

Patch propagates the error back to wdt_init().
