[rfc, PATCH v1 1/1] platform/x86: intel: Add 'intel' prefix to the modules automatically

[Andy Shevchenko]

Rework Makefile to add 'intel' prefix to the modules automatically.
This removes a lot of boilerplate code in it and also makes robust
against mistypos in the prefix.

Send as RFC because TBH I rather want to have something like this to be
available on the level of Kbuild for any of the subdirectories in
question. Also I haven't done any comprehensive build tests on this,
let's see what CIs think about this...
