[PATCH] platform/x86: handle Intel CPUs falsely reporting as GenuineIotel

[git@evalyngoemer.com]

From: Evalyn Goemer <git@evalyngoemer.com>

Certain Intel CPUs have a bit flipped in the CPUID string causing them
to report as "GenuineIotel" leading to them potentially not being detected
properly as an Intel CPU.

This patch fixes this by adding the "GenuineIotel" string to the
intel_cpu_dev.c_ident array inside the arch/x86/kernel/cpu/intel.c file.

This issue can be found as existing here:
