c5d66587b8 net: ethernet: mediatek: ppe: fix busy wait loop
The intention is for the loop to timeout if the body does not succeed.
The current logic calls time_is_before_jiffies(timeout) which is false
until after the timeout, so the loop body never executes.

Fix by using readl_poll_timeout as a more standard and less error-prone
solution.

ba37b7caf1 net: ethernet: mtk_eth_soc: add support for initializing the PPE
The PPE (packet processing engine) is used to offload NAT/routed or even
bridged flows. This patch brings up the PPE and uses it to get a packet
hash. It also contains some functionality that will be used to bring up
flow offloading.
