lan78xx: Change LEDs to include 10Mb activity

The default LED modes put 1000Mb/activity on orange and 100Mb/activity
on green, but this leaves no indication for a 10Mb link. Change the
defaults to put 10Mb/100Mb/activity on green.

dwc_otg: remove unnecessary dma-mode channel halts on disconnect inte…

…rrupt

Host channels are already halted in kill_urbs_in_qh_list() with the
subsequent interrupt processing behaving as if the URB was dequeued
via HCD callback.

There's no need to clobber the host channel registers a second time
as this exposes races between the driver and host channel resulting
in hcd->free_hc_list becoming corrupted.

clk: bcm2835: Limit PCM clock to OSC and PLLD_PER

It is unwise to use sources other than the oscillator and PLLD_PER for
the PCM peripheral (and perhaps others - TBD) because their rate can
change and they may even be switched off, so explicitly restrict the
choice using dummy entries in the list of potential parents (item index
is significant).
