spi: dw-mid: change magic numbers to the constants
Instead of using magic numbers in the code we create a bit map definition of
the DMACR register and use it.
There is no functional change.

spi: dw-mid: remove redundant dmac member
Instead of using that member we prefer to use dma_dev which represents actual
struct device of the DMA device.

spi: dw: remove FSF address
There is no need to keep FSF address in the head of the file. While here, fix
few typos in the header.

unused dw_spi iolen field.

spi: spi-dw: fix all sparse warnings
The dw_{read,write}[lw] macros produce sparse warnings everytime they
are used. The "read" ones cause:
warning: cast removes address space of expression
warning: incorrect type in argument 1 (different address spaces)
expected void const volatile [noderef] <asn:2>*addr
got unsigned int *<noident>
And the "write" ones:
warning: cast removes address space of expression
warning: incorrect type in argument 2 (different address spaces)
expected void volatile [noderef] <asn:2>*addr
got unsigned int *<noident>
Fix this by removing struct dw_spi_reg and converting all the register
offsets to #defines. Then convert the macros into inlined functions so
that proper type checking can occur.
While here, also fix the three sparse warnings in spi-dw-mid.c due to
the return value of ioremap_nocache being stored in a u32 * not a
void __iomem *.
With these changes the spi-dw* files all build with no sparse warnings.

spi: reorganize drivers
Sort the SPI makefile and enforce the naming convention spi_*.c for
spi drivers.
This change also rolls the contents of atmel_spi.h into the .c file
since there is only one user of that particular include file.
v2: - Use 'spi-' prefix instead of 'spi_' to match what seems to be
be the predominant pattern for subsystem prefixes.
- Clean up filenames in Kconfig and header comment blocks
