e8531ac8b2 clk: at91: fix num_parents test in at91sam9260 slow clk implementation
The slow clk block provided by at91sam9260 and derived SoCs should always
have 2 parents.

80eded6ce8 clk: at91: add slow clks driver
AT91 slow clk is a clk multiplexer.

In some SoCs (sam9x5, sama5, sam9g45 families) this multiplexer can
choose among 2 sources: an internal RC oscillator circuit and an oscillator
using an external crystal.

In other Socs (sam9260 family) the multiplexer source is hardcoded with
the OSCSEL signal.
