hal: ra: Add source code for supporting custom eth phy driver

This update is for Ethernet driver to better fit into Zephyr
standard.
Add in ETHER_CFG_USE_CUSTOM_PHY_DRIVER to Ethernet controller
driver to skip the phy control and allow the use of Zephyr
phy driver.
Add phy link speed to Ethernet controller driver instance
control.
Add phy_lsi_address to Ethernet phy instance control to
allow the control of phy address as input

      Add phy link speed to Ethernet controller driver instance control.
      Remove static definition of some internal function is ethernet driver to allow their usage in Zephyr side
-     Add phy_lsi_address to Ethernet phy instance control to allow the control of phy address as input.
      Remove the phy target settings as they are not used.
