clk: vc5: Add support for 5P49V60

The 5P49V60 is very similar to the existing supported clock chips of the
versaclock5 driver and uses the same register map layout. But its maximum
VCO frequency is 2.7 GHz instead of 3 GHz for the other supported devices.

Add a vco_max field to the chip info field to allow to specify a per device
variant maximum VCO frequency.
