mb/siemens/mc_apl1: Move POST logic to mainboard level

Move logic previously used only in the mc_apl2 variant to
the mainboard level so that other variants can also make
use of it without code duplication.

This functionality on the mc_apl6 variant will be enabled
in a follow-up patch.

BUG=none
TEST=Boot on siemens/mc_apl2 and observe that the POST
codes are displayed before DRAM training.
