Wolfram Sang 0b38fffbe4 mtd: nand: mxs: reset BCH earlier, too, to avoid NAND startup problems 
It could happen (1 out of 100 times) that NAND did not start up correctly after
warm rebooting, so we end up with various failures or DMA timed out due to a
stalled BCH. When resetting BCH together with GPMI, the issue could not be
observed anymore (after 10000+ reboots). We probably need the consistent state
already before sending commands to NAND. This behaviour was observed in barebox
and kernel, so I assume it affects U-Boot as well. I chose to keep the extra
reset for BCH when changing the flash layout to be on the safe side.
