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).
