[PATCH 0/2] x86: apl: Add support for different number of cores

Currently the Apollo Lake implementation of cpu_ops.get_count returns
a hardcoded value of 4.

The function cpu_x86_get_count() provides a more generic implementation
that reads the number of cores from device tree. But this function is
currently static.

This series:
 - makes cpu_x86_get_count() non-static
 - drops the Apollo Lake specific get_count implementation and
   uses cpu_x86_get_count() instead

With the changes in this series also Apollo Lake variants with
a different number of cores boot correctly.

  x86: apl: Use cpu_x86_get_count() for cpu_ops.get_count
