[meta-xilinx] [PATCH] mtd: nand: Arasan: Fix initialization of controller structure

[Martin Lund]

Make sure that the controller structure is initialized using the
nand_hw_control_init() function. This way the spinlock, waitqueue
elements etc. of the structure will be correctly initialized.

Without this fix the nand driver have been seen stalling, especially
when stress tested.
