vendorcode/intel: Rework UDK binding Kconfig

coreboot code currently supports different UDK binding as per
underlying FSP requirement, example: ICL and TGL uses
UDK_2017_BINDING while ADL uses UDK_202005_BINDING Kconfig.

These UDK binding Kconfigs are being used to choose the correct
UDK_VERSION.

This patch introduces `UDK_BASE` Kconfig option so UDK_VERSION
if clause don't need to add specific UDK binding Kconfig everytime with
introduction of newer UDK bindings in future.

Tested with BUILD_TIMELESS=1, Hatch remains identical.
