bl32: sp_min: reduce the alignment for fconf_populator

sp_min.ld.S is used for aarch32.

ALIGN(4) is used for alignment of the other structures. I do not think
struct fconf_populator is a special case. Let's use ALIGN(4) here too.

Perhaps, this is just a copy-paste mistake of commit 26d1e0c3


("fconf: necessary modifications to support fconf in BL31 & SP_MIN").
