ARM: nommu: fix warning with checksyscalls.sh

CALL    scripts/checksyscalls.sh
<stdin>:46:1: warning: "__IGNORE_migrate_pages" redefined
In file included from <stdin>:2:
arch/arm/include/asm/unistd.h:482:1: warning: this is the location of the previous definition

This is caused because we define __IGNORE_migrate_pages to be 1, but in
the case of nommu, it's defined to be empty.  Fix this by just defining
the __IGNORE_ symbols to be empty.
RT99759: Upgrade Ethernet device driver in Linux Kinetis.
Changes to the kernel.
RT99759: Added a delay after the reset in fec_stop. Without that delay,
suspend-to-ram doesn't suspend for some reason.
