[PATCH V2 1/3] net: phy: broadcom: use auxctl reading helper in BCM54612E code

[Rafał Miłecki]

From: Rafał Miłecki <ra...@milecki.pl>

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).
