net: phy: realtek: Fix rtl8211f_config_init() for RTL8211F(D)(I)-VD-CG PHY
Commit bb726b753f75 ("net: phy: realtek: add support for RTL8211F(D)(I)-VD-CG") extended support of the driver from the existing support for RTL8211F(D)(I)-CG PHY to the newer RTL8211F(D)(I)-VD-CG PHY. While that commit indicated that the RTL8211F_PHYCR2 register is not supported by the "VD-CG" PHY model and therefore updated the corresponding section in rtl8211f_config_init() to be invoked conditionally, the call to "genphy_soft_reset()" was left as-is, when it should have also been invoked conditionally. This is because the call to "genphy_soft_reset()" was first introduced by the commit 0a4355c2b7f8 ("net: phy: realtek: add dt property to disable CLKOUT clock") since the RTL8211F guide indicates that a PHY reset should be issued after setting bits in the PHYCR2 register. As the PHYCR2 register is not applicable to the "VD-CG" PHY model, fix the rtl8211f_config_init() function by invoking "genphy_soft_reset()" conditionally based on the presence of the "PHYCR2" register.
