ice: Implement PTP support for E830 devices
Add specific functions and definitions for E830 devices to enable
PTP support.
E830 devices support direct write to GLTSYN_ registers without shadow
registers and 64 bit read of PHC time.
Enable PTM for E830 device, which is required for cross timestamp and
and dependency on PCIE_PTM for ICE_HWTS.
Check X86_FEATURE_ART for E830 as it may not be present in the CPU.
