crypto: caam - add support for i.MX8M Nano

Browse source 
Add support for the crypto engine used in i.mx8mn (i.MX 8M "Nano"),
which is very similar to the one used in i.mx8mq, i.mx8mm.

Since the clocks are identical for all members of i.MX 8M family,
simplify the SoC <--> clock array mapping table.
