v2 cover arc: some allmodconfig build fixes

From: Randy Dunlap <[email protected]>

Hi,

Here are a few patches that fix build errors or warnings that I encountered while doing arc "allmodconfig" builds.

These patches do not fix all of the build issues.

PATCH v2 1/4 arc: fix build errors in arc/include/asm/delay.h

Fix build errors in arch/arc/'s delay.h:
- add "extern unsigned long loops_per_jiffy;"
- add <asm-generic/types.h> for "u64"

PATCH v2 3/4 arc: fix data type errors in platform headers

In reply to rd_dunlab

From: Randy Dunlap <[email protected]>

Add <asm-generic/types.h> to fix build errors.
Both ctop.h and <soc/nps/common.h> use u32 types and cause many errors.

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.

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.
