For INTEL_MEI_LATE_BIND to work we also need  INTEL_MEI_GSC, which is 
the config for the mei child device and depends on the config for our 
driver, so a "depends on" tag would go circular.
INTEL_MEI_GSC also has further dependencies, so if we wanted to "select" 
it (instead of marking it with a "depends on") we'd have to select those 
dependencies as well, which doesn't scale well.
This patch only works as-is because our CI config does enable 
INTEL_MEI_GSC with all its dependencies.

For other mei components (e.g. PXP, HDCP) what we did was notify the 
distros that they had to enable the option in their kernel builds if 
they wanted the feature to be enabled, so the idea was to do the same here.

Unless there is a kconfig trick we're missing that would make this work?
