[PATCH v3 25/31] mtd: mpc5121_nfc: remove now obsolete clock lookup name

[Gerhard Sittig]

after device tree based clock lookup became available, the NAND flash
driver need no longer use the previous "nfc_clk" name but can switch to
the fixed "per" clock name -- adjust the peripheral driver and remove
the clock driver's clkdev registration
