clk: vc5: Add support for IDT VersaClock 5P49V6901

Update IDT VersaClock 5 driver to support IDT VersaClock 6 5P49V6901.
This chip has two clock inputs (external XTAL or external CLKIN), four
fractional dividers (FODs) and five clock outputs (four universal clock
outputs and one reference clock output at OUT0_SELB_I2C).
