Subject: [PATCH -next] 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.

Fixes: 317aeb83c92b ("scsi: lpfc: Add blk_io_poll support for latency improvment")
