arm64: dts: altera: socfpga_stratix10: update internal oscillators

Add the clock-frequency property to the cb_intosc_ls_clk and
cb_intosc_hs_div2_clk device tree nodes.

The f2s_free_clk is implemented by custom logic in the FPGA; so it
should be disabled in the dtsi by default and enabled by a
dts for a specific FPGA design on a specific board.
