[RFC V2 1/3] common: move DDR_SPD to common/Kconfig

[Renaud Barbier]

There may be an issue in the future. DDR_SPD selects the PPC Freescale
DDR driver support (my fault for this bad choice). If somebody was to
add and build a PPC machine with DDR support that is none of the
Freescale boards then the Freescale DDR driver will be selected too.

To be safe, something like that could be used:

diff --git a/arch/ppc/mach-mpc85xx/Makefile b/arch/ppc/mach-mpc85xx/Makefile
index 3e64617..a7453f7 100644
