[PATCH -next] usb: gadget: udc: atmel: remove unused variable 'pp'

[Wei Yongjun]

Gcc report build warning as follows:

drivers/usb/gadget/udc/atmel_usba_udc.c:2106:22: warning:
 variable pp set but not used [-Wunused-but-set-variable]
 2106 |  struct device_node *pp;
      |                      ^~

After commit e78355b577c4 ("usb: gadget: udc: atmel: Don't
use DT to configure end point"), variable 'pp' is never used,
so removing it to avoid warning.
