Since commit 188db4435ac6 ("usb: gadget: s3c: use platform resources"),
'request_mem_region()' and 'ioremap()' are no more used, so they don't need
to be undone in the error handling path of the probe and in the remove
function.

Remove these calls and the unneeded 'rsrc_start' and 'rsrc_len' global
variables.

Fixes: 188db4435ac6 ("usb: gadget: s3c: use platform resources")
