lib: Allow MD5 to be enabled in SPL
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.

+ This option enables MD5 support. MD5 is an algorithm designed

+ 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.
