drivers/intel/fsp2_0: Remove fsp_find_smbios_memory_info() from FSP2.0 driver

Browse Source 
As per FSP 2.0 specification and FSP SOC integration guide, its not expected
that SMBIOS Memory Information GUID will be same for all platform. Hence
fsp_find_smbios_memory_info() function inside common/driver code is not
generic one.

Removing this function and making use of fsp_find_extension_hob_by_guid()
to find SMBIOS Memory Info GUID from platform code as needed.
