[PATCH u-boot v2019.04-aspeed-openbmc] Revert "configs: disable dcache on ast2500 evb"

[Lei YU]

This reverts commit c1bfa87b767b2dc532cedc00f561bf6433fe30c7.

Disabling DCACHE on ast2500 causes significant performance drop and it
gets watchdog timeout during normal boot.

Revert the commit to make it behave normal as before.
