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).

V2: - Reword the commit message to explicitly mention the VC5 driver
and the added support for VC6.
- Mention VC6 in Kconfig
V3: None
