arc: [plat-eznps] fix printk warning in arc/plat-eznps/mtm.c 

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

In file included from ../include/linux/printk.h:7,
                 from ../include/linux/kernel.h:14,
                 from ../include/linux/list.h:9,
                 from ../include/linux/smp.h:12,
                 from ../arch/arc/plat-eznps/mtm.c:17:
../arch/arc/plat-eznps/mtm.c: In function 'set_mtm_hs_ctr':
../include/linux/kern_levels.h:5:18: warning: format '%d' expects argument of type 'int', but argument 2 has type 'long int' [-Wformat=]

                  ^~~~~~

   ^~~~~~
../arch/arc/plat-eznps/mtm.c:166:40: note: format string is defined here
   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.
