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 SoCs affected by upcoming changes and by that PMC_MAIN + x hack, others could follow by the same scheme. 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.
