Jonas Gorski 1a2e8d8f27 brcm63xx: prevent usb clock state inconsistency on BCM6318
Return the same clock for usbh and usbd on BCM6318 to prevent the clock
getting disabled despite being supposed to be enabled, e.g. by the
following sequence:

	clk_enable(usbh); <- usbh->usage = 1, enabled
	clk_enable(usbd); <- usbd->usage = 1, enabled (no effect)
	clk_disable(usbd); <- usbd->usage = 0,  -> disabled!

Florian Fainelli b3476a2a89 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.
