mtd: atmel_nand: replace cpu_is_at32ap7000() with a nand platform data

The nand driver use cpu_is_at32ap7000() macro for a workaround. For the
multi-platform support, we will remove this cpu_is_xxx() macro.

This patch adds a boolean variable need_reset_workaround in structure
atmel_nand_data. Using this variable we can remove cpu_is_at32ap7000() macro.

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.
