net: ethernet: ti: j721e-cpsw-virt-mac: add sw irq coalescing based on hrtimers
Add SW IRQ coalescing based on hrtimers for RX/TX data path which can be
enabled by ethtool commands:
ethtool -C eth1 tx-usecs 50
ethtool -C eth1 rx-usecs 50
min value is 20us
Comapring to gro_flush_timeout, napi_defer_hard_irqs this patch allows to
enable IRQ coalesing per RX/TX path separately.
