[v4,09/27] lmb: allow lmb module to be used in SPL

With the introduction of separate config symbols for the SPL phase of
U-Boot, the condition checks need to be tweaked so that platforms that
enable the LMB module in SPL are also able to call the LMB API's. Use
the appropriate condition checks to achieve this.
