The NAND flash memory populated on Colibri VF61 allows faster NAND timings than the flash memory on VF50. Additionally, due to divider limitations, VF61 did clock the flash even slower than VF50. Assign the NFC clock in the module specific device trees vf500-colibri.dtsi and vf610-colibri.dtsi respectively. This increases raw read speed on Colibri VF61 by about 20%.
