net: ethernet: ti: am65-cpsw: Handle -EPROBE_DEFER for Serdes PHY
In the am65_cpsw_init_serdes_phy() function, the error handling for the
call to the devm_of_phy_get() function misses the case where the return
value of devm_of_phy_get() is ERR_PTR(-EPROBE_DEFER). Proceeding without
handling this case will result in a crash when the "phy" pointer with
this value is dereferenced by phy_init() in am65_cpsw_enable_phy().
Fix this by adding appropriate error handling code.
