Subject: [PATCH v3 02/19] dt-bindings: clock: at91: Split up per SoC partially

Before adding even more new indexes creating more holes in the
clk at91 drivers pmc_data->chws arrays, split this up.

This is a partial split up only for some of the old PMC definitions.

Binding splitup was proposed for several reasons:

1) keep the driver code simple, readable, and efficient
2) avoid accidental array index duplication
3) avoid memory waste by creating more and more unused array members.

Old values are kept to not break dts, and to maintain dt ABI.

Notes:
    v3:
    - full splitup for all at91 family SoCs instead of just a few
    
    v2:
    - new patch, not present in v1
