mb/siemens/mc_ehl4: Make DRAM population depending on GPIO GPP_B5
GPIO GPP_B5 is used as input on this mainboard. For a full-populated
DRAM configuration, the input signal is connected to ground and for a
half-populated configuration it is connected to 3.3 V.
BUG=none
TEST=Use different HW configurations and check coreboot log
GPP_B5 = 0:
[DEBUG] 2 DIMMs found
GPP_B5 = 1:
[INFO ] meminit_channels: DRAM half-populated
[DEBUG] 1 DIMMs found
