The Blackfin SPORT peripheral is a pretty flexible device.  With enough
coaching, we can make it generate SPI compatible waveforms.  This is
desirable as the SPORT can run at much higher clock frequencies than the
dedicated on-chip SPI peripheral, and it can do full duplex DMA.  It also
opens up the possibility of multiple SPI buses in case someone wants to
dedicate a whole bus to a specific part that does not play well with
others.

This patch includes below fixes:
1. Add missing device_remove_file for dev_attr_status_show in tle62x0_remove.
2. Fix tle62x0_probe error handling:
   Currently, if the error happens when ptr > 0, gpio_attrs[0] is not
   properly remove.

  spi/dw_spi: unify the low level read/write routines

With the addition of a device platform mfd_cell pointer, MFD drivers
can go back to passing platform data back to their sub drivers.
This allows for an mfd_cell->mfd_data removal and thus keep the
sub drivers MFD agnostic. This is mostly needed for non MFD aware
sub drivers.

If pl022_dma_probe fails, we can try to transfer data in polling or interrupt
mode. Also, set platform_info->enable_dma to 0, so that no other code tries to
use dma.

Calling spi_bitbang_stop() will also destroy bitbang->workqueue,
which is created by calling spi_bitbang_start() in s3c24xx_spi_probe().

spi_master_put() should only be used in error handling.
Once spi_register_master() returns success, we should call
spi_unregister_master() instead.
