Subject: [PATCH v1 1/1] cpuidle: Update header inclusion

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

drivers/cpuidle/poll_state.c:52:2: error: call to undeclared library function 'snprintf' with type 'int (char *restrict, unsigned long, const char *restrict, ...)'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]

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