Since we need to provide a value for all the other parameters anyway, avoiding TPR6 makes no real difference. To make matters worse, TPR6 is a compound value covering multiple DRAM types, but also spans over three SoCs, which makes it hard to find one good default value. Drop the default from Kconfig, and put some explicit values in the defconfigs for the few boards that were relying on the default so far. The value is taken from one BSP, only the lower byte matters anyway for those boards, all using DDR3 DRAM.
