[PATCH v2 1/1] platform/x86: intel: Add 'intel' prefix to the modules automatically

[Andy Shevchenko <andriy.shevchenko@linux.intel.com>]

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.

Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com>

v2: fixed obvious typos (LKP), Cc'ed to Kbuild ML (Ilpo), dropped RFC marker

Note to Kbuild people: TBH I rather want to have something like this
to be available on the level of Kbuild for any of the subdirectories
in question.
