siemens/mc_apl1: Make DRAM configuration more flexible 

By storing the FSP-M DRAM configuration parameter in the hwinfo block,
one becomes more flexible in case of a change of the DRAM type.
The configuration data from hwinfo block is a one-to-one representation
of the FSPM_UPD data starting with parameter 'Package' (offset 0x4d) and
ending before parameter 'Ch0_Bit_swizzling' (offset 0x88).
