sunxi: H616: dram: drop default TPR6 Kconfig value
CONFIG_DRAM_SUNXI_TPR6 is the only DRAM config parameter that has a
non-zero default value. 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.
