For E822, the time value in Rx Flex Descriptors is 0 due to the
missing PHY clock timer setup. Also, the source clock index in use
is based on device capabilities instead of always being zero.
Fixes: 953e74e6b73a ("net/ice: enable Rx timestamp on flex descriptor")
Fixes: 646dcbe6c701 ("net/ice: support IEEE 1588 PTP")
Fixes: fb800fde66f4 ("net/ice/base: work around missing PTP capabilities")
