calibrate: update header inclusion

While cleaning up some headers, I got a build error on this file:

init/calibrate.c:20:9: error: call to undeclared function 'kstrtoul'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]

Update header inclusions to follow IWYU (Include What You Use) principle.
