brcm63xx: fix USB gadget build failure after 6345 Ethernet
While adding support for BCM6345 Ethernet, some changes in the macros ENETDMA{C,S} where introduced which now make the bcm63xx USB gadget driver fail to build. Fix this. Signed-off-by: Florian Fainelli <florian@openwrt.org> SVN-Revision: 39279
