scsi: lpfc: Add dependency on CPU_FREQ

Since commit 317aeb83c92b ("scsi: lpfc: Add blk_io_poll support for latency
improvment"), the lpfc driver depends on CPUFREQ. Without it, builds fail
with

drivers/scsi/lpfc/lpfc_sli.c: In function 'lpfc_init_idle_stat_hb':
drivers/scsi/lpfc/lpfc_sli.c:7329:26: error:
	implicit declaration of function 'get_cpu_idle_time'

Add the missing dependency.
