There is no really generic way to configure the S3C2440 CPU with fits to all

The generic A9M2440 comes in many SDRAM variantes. Two GPIO pins describing
the populated SDRAM devices. This patch adds some code to query the setting
and setup a correct SDRAM configuration out of four possible variants.
Due to the lack of hardware the 16 MiB and 128 MiB case is untested yet.
Due to the 32 MiB configuration we must link the u-boot-v2 always to
address 0x31fc0000. Even for the 64 MiB and 128 MiB configuration.

We used to initialize the PLLs on PCM038 in two
steps. The first was to initialize a basic setup
so that all peripheral clocks run at their final
speed and the second step was to push the processor
to full speed after the PMIC has been initialized
for the higher voltage.
Do this in one step instead to get an easier setup.
