net/phy/marvell: Expose IDs and flags in a .h and add dns323 LEDs setup flag

This moves the various known Marvell PHY IDs to include/linux/marvell_phy.h
along with dev_flags definitions for use by the driver.

I then added a flag that changes the PHY init code to setup the LEDs
config to the values needed to operate a dns323 rev C1 NAS.

I moved the existing "resistance" flag to the .h as well, though I've
been unable to find whoever sets this to convert it to use that constant.
