There is no reason to have these two kernel modules separate. Having
them merged into one kernel module also slightly reduces memory
consumption and module load times a little.

mapped size (lsmod):
         before:             after:
    sec_core   20480    sec_core   24576
    sec_irq    16384
    ----------------
    total      36864

Section sizes (size -A):
         before:             after:
    sec_core    6780    sec_core   13239
    sec_irq     8046
    ----------------
    Total      14826

Checkpatch suggests to update MAINTAINERS, but the new file is covered
already due to using a wildcard.
