Remove clock-frequency (surely PCIe is not running at 33 MHz).

Do these inline the way the example shows.Sorry, Scott, I just remember in this way, the node can't be recognized by = system when run Uboot. The include can't be in the crypto@80000. See the di= scussion in http://git.am.freescale.net:8181/#/c/736/ . Maybe I should re-modify the example file.
