mtd: nand: pxa3xx: Set info->use_dma properly
Currently, the variable info->use_dma is never set and always
zero-valued which means the driver never does DMA transfers.
We fix this by simply setting info->use_dma to the module parameter,
also named 'use_dma'. Note that the module parameter has the same name,
but different semantics.
This fixes a regression introduced by the below commit
which removed the info->use_dma variable set.

mtd: pxa3xx_nand: unify prepare command
Before the above commit, the driver had use_dma=1 on all NAND commands
except on CMD_STATUS. This behavior is long lost and we are not
recovering in this patch, either.
This was spotted and verified by human inspection.
