soc/intel/jasperlake: Add initial chipset.cb

Browse source 
Similar to other Intel SoCs, create a chipset.cb for Jasperlake
giving alias names to all known PCI devices. Taken from comments in
existing JSL board devicetrees, cross-referenced against the publicly
available JSL EDS.

At the same time, remove the usb2_lte device aliases in the BOTEN and
DRAWCIA dedede variants, and replace their references with the new
usb2_port4 alias, since we can only have a single alias per device.

TEST=build boten and drawcia dedede variants
