lib/spd_bin: Tweak the log
Correct the missing log. Should be the part number not just part.

cpu/x86/smm: Add smm_size to relocatable smmstub
To mitigate against sinkhole in software which is required on
pre-sandybridge hardware, the smm entry point needs to check if the
LAPIC base is between smbase and smbase + smmsize. The size needs to
be available early so add them to the relocatable module parameters.
When the smmstub is used to relocate SMM the default SMM size 0x10000
is provided. On the permanent handler the size provided by
get_smm_info() is used.
