Hi Jonathan, all,

This series adds support for sama7g5.
The last patch (4/4) adds the support.

The sama7g5 is slightly different from sama5d2, but has the same basic
operations. The register map is a bit different, so, I added some primitives
to differentiate between the two classes of hardware blocks (sama5d2-sam9x60
and sama7g5).

Sama7g5 has 16 channels ADC, no resistive touch, and extra features
(FIFOs, better oversampling , not implemented yet).

I had to chop through the driver to add support for sama7g5, so, let me
know what you think, if something would need changing.

Thanks,
Eugen
