Hi,

As described in patch 3/4 when receiving WoL packet on Ethernet
interfaces of AT91 SoCs and being in ULP0 or ULP1 AT91 specific power
management modes some SoCs may block other may have Ethernet interfaces
broken after resume. Workaround for this would be to disable clocks
for these Ethernet interfaces. As the MACB driver is common to multiple
vendors and multiple architectures and ULP0, ULP1 PM modes are AT91
specific the fix has been implemented in arch/arm/mach-at91 to avoid
having AT91 specific code in MACB driver.

Along with this patches I took the chance and added few comment style
fixups.

Thank you,
Claudiu Beznea
