[ Upstream commit 9e2ea405543d9ddfe05b351f1679e53bd9c11f80 ]

Fix printk format warning in arch/arc/plat-eznps/mtm.c:

                 from ../include/linux/kernel.h:14,

                 from ../arch/arc/plat-eznps/mtm.c:17:
../arch/arc/plat-eznps/mtm.c: In function 'set_mtm_hs_ctr':

   ^~~~~~

   pr_err("** Invalid @nps_mtm_hs_ctr [%d] needs to be [%d:%d] (incl)\n",

                                       %ld
The hs_ctr variable can just be int instead of long, so also change
kstrtol() to kstrtoint() and leave the format string as %d.

Also add 2 header files since they are used in mtm.c and we prefer
not to depend on accidental/indirect #includes.
