phy: marvell: Fix and unify reg-init behavior

For the Marvell 88E1510, marvell_of_reg_init was called too late, in the
config_aneg function.
Since commit 113c74d8 ("net: phy: turn carrier off on phy attach"),
this lead to the link not coming up at boot anymore, due to the phy
state machine being stuck at waiting for interrupts (off by default on
the 88E1510).
For seven other Marvell PHYs, marvell_of_reg_init was not called at all.

Add a generic marvell_config_init function, which in turn calls
marvell_of_reg_init.
PHYs, which already have a specific config_init function with a call to
marvell_of_reg_init, are left untouched. The generic marvell_config_init
function is called for all the others, to get consistent behavior across
all Marvell PHYs.
