net: phy: broadcom: use auxctl reading helper in BCM54612E code
Starting with commit 5b4e29005123 ("net: phy: broadcom: add bcm54xx_auxctl_read") we have a reading helper so use it and avoid code duplication. It also means we don't need MII_BCM54XX_AUXCTL_SHDWSEL_MISC define as it's the same as MII_BCM54XX_AUXCTL_SHDWSEL_MISC just for reading needs (same value shifted by 12 bits).
