During a bug hunt that ultimately turned out unrelated to the state of the barebox at91 clk driver, I synchronized its state with Linux v5.6. This imports it, after cleanup. It refactors other code a bit to reduce the diff for the final port and future ones. What we gain from this: - bug fixes that have been posted upstream in the meanwhile - sam9x60 (new Microchip ARM926EJ-S) clock support - sama5d2 audio PLL - Some more helpers to make code porting slightly easier -
