ice: introduce ice_pf_src_tmr_owned

Add ice_pf_src_tmr_owned() macro to check the function capability bit
indicating if the current function owns the PTP hardware clock. This is
slightly shorter than the more verbose access via
hw.func_caps.ts_func_info.src_tmr_owned. Use this where possible rather
than open coding its equivalent.
