net: phy: ti: Use default values for tx/rx delay and fifo size
When not using DM_ETH, these PHY settings are programmed with default values hardcoded into the driver. When using DM_ETH, they should come from the device tree. However, if the device tree does not have the properties, the driver will silent use -1. Which is entirely out of range, programs nonsense into the PHY's registers, and does not work. Change this to use the same defaults as non-DM_ETH if the device tree is lacking the properties. As an alternative, the kernel driver for the phy will display an error message and fail if the device tree is lacking.
