[meta-ti] [PATCH] dra7xx-evm.conf: removing am57xx SOCS from PDK

[Denys Dmytriyenko]

I assume, you want this merged into morty too, correct?

This change is fine with me, but I'd go even further and move setting initial 
TI_PDK_LIMIT_SOCS from omap-a15.inc into am57xx-evm.conf 


Jake,

Do you have any comments?
