Boards used to specify zreladdr in their Makefile.boot with
zreladdr-y := x, so conflicting zreladdrs were silently overwritten.
This patch changes this to zreladdr-y += x, so that we end
up with multiple words in zreladdr in such a case. We can
detect this later and complain if necessary.

Software defined version number is not stable enough to be used
in device type naming scheme.  The patch changes it to use implicit
soc name for spi device type definition.  In this way, we can easily
align the naming scheme with device tree binding, which comes later.

It removes fifosize from spi_imx_data and adds devtype there, so that
fifosize can be set in an inline function according to devtype.
Also, cpu_is_mx can be replaced by inline functions checking devtype.

It is not good to have cpu_name and to_version encoded into sdma
firmware name as variables.  For example, there are three TOs of
imx51 soc, the sdma script never changes since TO1, which means
all three TOs of imx51 uses TO1 version of sdma script.  But we
have to prepare three identical firmwares, sdma-imx51-to1.bin
sdma-imx51-to2.bin and sdma-imx51-to3.bin, to have the kernel
capable of running on all three TOs.

The patch removes cpu_name and to_version from sdma platform data,
and instead uses fw_name to pass the firmware name, so that we can
pass the TO version where it's relevant and skip it where only one
firmware exists.
