ARM: at91: sama5d3xek: reserve dma channel for audio

We set the DMA configuration on USARTs in the SoC DT in (ARM: at91: sama5d3:
add usart dma configurations). As the audio must work with DMA channels, we
reserve some dma channels for audio, or else audio won't work.

ARM: at91/dt: at91sam9rl: switch ssc compatible string

As the SSC integrate in at91sam9rl support frame sync length
extension, so switch compatible string to support this feature.

Declare the SCKC (Slow Clock Configuration) block and its clks.
Make use of the clk32k clk instead of slow_osc where appropriate.

Retrieve the NFC clock to make sure it is enabled. Make that optional to ensure

device trees will include it.
