[RFC PATCH 7/7] ARM: dts: vf610-twr: Enable QSPI and map flash devices.

[Cory Tusar <cory.tusar-J6Z/VSE8EyIAspv4Qr0y0gC/G2K4zDHf@public.gmane.org>]

This commit enables the qspi0 functional block, and maps the two
flash devices connected to QSPI0_A_CS0 and QSPI0_B_CS0 to individual MTD
devices.

Tested using mtd_readtest, mtd_speedtest, and mtd_stresstest on a Rev. H
TWR board.
