aspeed_sdmc: Set 'cache initial sequence' always true 

The SDRAM training routine sets the 'Enable cache initial' bit, and then
waits for the 'cache initial sequence' to be done.

Have it always return done, as there is no other side effects that the
model needs to implement. This allows the upstream u-boot training to
proceed on the ast2500-evb board.
