tree: Drop Intel Ice Lake support

Intel Ice Lake is unmaintained and the only user of this platform ever
was the Intel CRB (Customer Reference Board). As it looks like, it was
never ready for production as only engineering sample CPUIDs are
supported.

As announced in the 4.19 release notes, remove support for Intel
Icelake code and move any maintenance on the 4.19 branch.

This affects the following components and their related code:

  * Intel Ice Lake SoC
  * Intel Ice Lake CRB mainboard
  * Documentation
