brcm63xx: improve BCM6318 support
Provide clock toggling for the USB host and slave controller as well as for the Ethernet Switch. The bcm63xx_enetsw driver is changed not to use request_mem_region() as the Roboswitch register overlaps with the Roboswitch IUDMA channels, hence making the driver return -EBUSY. A future fix might be to use variable size RSET_ENETSW sizes depending on the chip we are targetting. Signed-off-by: Florian Fainelli <florian@openwrt.org> SVN-Revision: 39282
