x86/acpi/cstate: Improve Intel Family model checks

Browse source

Update the Intel Family checks to consistently use Family 15 instead of
Family 0xF. Also, get rid of one of last usages of x86_model by using
the new VFM checks.

Update the incorrect comment since the check has changed since the
initial commit:

  ee1ca48fae ("ACPI: Disable ARB_DISABLE on platforms where it is not needed")

The two changes were:

 - 3e2ada5867 ("ACPI: fix Compaq Evo N800c (Pentium 4m) boot hang regression")
   removed the P4 - Family 15.

 - 03a05ed115 ("ACPI: Use the ARB_DISABLE for the CPU which model id is less than 0x0f.")
   got rid of CORE_YONAH - Family 6, model E.
