The UCC Event Register (UCCE) already has unambigous macro definitions in qe.h,
so we should not be defining our own in the UCC Ethernet driver.

Removed unused local variable 'dev' from ucc_geth_poll(), which fixes
a warning caused by commit 908a7a16
("net: Remove unused netdev arg from some NAPI interfaces.").

Replaced in_be/out_be pairs with setbits32 or clrbits32, where applicable.
