ice: Add E830 device IDs, MAC type and registers

E830 is the 200G NIC family which uses the ice driver.

Add specific E830 registers. Embed macros to use proper register based on
(hw)->mac_type & name those macros to [ORIGINAL]_BY_MAC(hw). Registers
only available on one of the macs will need to be explicitly referred to
as E800_NAME instead of just NAME. PTP is not yet supported.
