With commit 47a4bea6af77b01d59a410d09a4c34b2dd14cf50 ("ARM: omap4:
Update sdram setting for panda rev A6") which attempted to "fix" Panda
ES B3 problem of a different DDR by checking for CPU revision and
changing configuration as per Panda for configuration that is common
for SDP4430 and Panda.

This resulted in all OMAP4430 SDP with processor boards > ES2.3 being
now broken. This does not obviously help the situation :). So fix it
by doing the missing DMM configuration needed for Panda as an override
of the weak function and revert the bad commit.

based on v2015.01-rc3 tag.
