usb: gadget: fsl_udc_core: fixup struct_udc_setup documentation 

The original implementation from commit b504882da5
("USB: add Freescale high-speed USB SOC device controller driver")
returned NULL on failure and an allocated + initialized struct fsl_udc on
success. The current code introduced in commit 4365831dad
("USB: fsl_usb2_udc: Get max ep number from DCCPARAMS register") only
provides partial initialization as well as returning 0 on success and -1
on failures. The function documentation is updated accordingly.
