[RFC PATCH net-next 2/2] powerpc: remove ehea driver references

[David Christensen <drc@linux.ibm.com>]

Follow-on cleanup after the removal of the IBM eHEA driver in commit
XXXXXXXXXXXX ("net: ethernet: ibm: remove the ehea driver").

Remove the CONFIG_IBM_EHEA entry from ppc64_defconfig and the obsolete
comment in arch/powerpc/mm/mem.c that referenced the driver.
