Subject: [PATCH] net: phy: broadcom: use auxctl reading helper in BCM54612E

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).
