usb: gadget: udc: atmel: handle at91sam9rl PMC

Browse Source 
[ Upstream commit bb80e4fa57eb75ebd64ae9be4155da6d12c1a997 ]

The at91sam9rl PMC is not quite the same as the at91sam9g45 one and now has
its own compatible string. Add support for that.

Fixes: 217bace8e548 ("ARM: dts: fix PMC compatible")
