lib: Allow MD5 to be enabled in SPL

Browse source 
At present the MD5 option cannot be enabled by board configs since it has
no Kconfig name. It is generally enabled, so long as FIT support is
present. But not all boards use FIT, particularly in SPL

Fix this and add an option for SPL as well. This allows board code to call
md5() even if FIT support is not enabled.

help
This option enables MD5 support. MD5 is an algorithm designed
in 1991 that produces a 16-byte digest (or checksum) from its input
data. It has a number of vulnerabilities which preclude its use in
security applications, but it can be useful for providing a quick
checksum of a block of data.
