This patch adds DMA support for the EP93xx SPI driver. By default the DMA is not enabled but it can be enabled by setting ep93xx_spi_info.use_dma to true in board configuration file. Note that the SPI driver still uses PIO for small transfers (<= 8 bytes) for performance reasons.

The ep93xx DMA controller has 10 independent memory to peripheral (M2P) channels, and 2 dedicated memory to memory (M2M) channels. M2M channels can also be used by SPI and IDE to perform DMA transfers to/from their memory mapped FIFOs. This driver supports both M2P and M2M channels with DMA_SLAVE, DMA_CYCLIC and DMA_MEMCPY (M2M only) capabilities.

Currently, both the WM8903 and TPS6586x chips attempt to register with gpiolib using the same GPIO numbers. This causes the audio driver to fail to initialize. To solve this, add a define to board-harmony.h for the TPS6586x, and make board-harmony-power.c use this define, instead of directly referencing TEGRA_NR_GPIOS.

With xfstest 254 I can panic the box every time with the inode number caching stuff on. This is because we clean the inodes out when we delete the subvolume, but then we write out the inode cache which adds an inode to the subvolume inode tree, and then when it gets evicted again the root gets added back on the dead roots list and is deleted again, so we have a double free. To stop this from happening just return 0 if refs is 0 (and we're not the tree root since tree root always has refs of 0). With this fix 254 no longer panics.

The current scrub implementation reuses bios and pages as often as possible, allocating them only on start and releasing them when finished. This leads to more problems with the block layer than it's worth. The elevator gets confused when there are more pages added to the bio than bi_size suggests.
