Add clk_rate parameter to platform data. If supplied, the
NOP phy driver will program the clock to that rate during probe.

Also add 2 flags, needs_vcc and needs_reset.
If the flag is set and the regulator couldn't be found
then the driver will bail out with -EPROBE_DEFER.

perf,x86: fix link failure for non-Intel configs

Commit 1d9d8639c063 ("perf,x86: fix kernel crash with PEBS/BTS after
suspend/resume") introduces a link failure since
perf_restore_debug_store() is only defined for CONFIG_CPU_SUP_INTEL:

arch/x86/power/built-in.o: In function `restore_processor_state':
(.text+0x45c): undefined reference to `perf_restore_debug_store'

Fix it by defining the dummy function appropriately.
