memory_info.h: Store SMBIOS error correction type

There are platforms that support error correction types other than
single-bit ECC. Extend meminfo to accomodate additional ECC types.

It is assumed that `struct memory_info` is packed to save space. Thus,
use `uint8_t` instead of an enum type (which are usually 4 bytes wide).
