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).

We had two defines for the same bit (both were used with the
MII_BCM54XX_AUXCTL_SHDWSEL_MISC register).

Please drop the other one and keep this one instead, the SHDWSEL prefix
is intentional and correct here since it matches the datasheet.

1) Use 0x%02x format for register number. This follows some other
defines and makes it easier to distinct register from values.
2) Put register define above values and sort the values. It makes
reading header code easier.
3) Drop SHDWSEL_ name part from the only value define using it. For all
other values we just start with MISC_.

That's not how these bits are defined in the data sheet, so please drop
that part of the patch.
