mlxsw: Add support for physical hardware clock

Shalom says:

This patchset adds support for physical hardware clock for Spectrum-1
ASIC only.

Patches #1, #2 and #3 add the ability to query the free running clock
PCI address.

Patches #4 and #5 add two new register, the Management UTC Register and
the Management Pulse Per Second Register.

Patch #6 publishes scaled_ppm_to_ppb() to allow drivers to use it.

Patch #7 adds the physical hardware clock operations.

Patch #8 initializes the physical hardware clock.

Patch #9 adds a selftest for testing the PTP physical hardware clock.

v2 (Richard):
* s/ptp_clock_scaled_ppm_to_ppb/scaled_ppm_to_ppb/
* imply PTP_1588_CLOCK in mlxsw Kconfig
* s/mlxsw_sp1_ptp_update_phc_settime/mlxsw_sp1_ptp_phc_settime/
* s/mlxsw_sp1_ptp_update_phc_adjfreq/mlxsw_sp1_ptp_phc_adjfreq/
