perf/amd/ibs: Add ->check_period() callback
IBS Fetch and IBS Op PMUs have constraints on sample period. The sample
period is verified at the time of opening an event but not at the ioctl()
interface. Hence, a user can open an event with valid period but change
it later with ioctl(). Add a ->check_period() callback to verify the
period provided at ioctl() is also valid.
