refactor(drivers/marvell/comphy-3700): rename Digital Loopback Enable register constant

Browse source 
The register at offset 0x23 is called Digital Loopback Enable, but the
constant is COMPHY_LOOPBACK_REG0, as if there were some LOOPBACK_REG1
register or something, which there is not.

Rename the constant to COMPHY_DIG_LOOPBACK_EN.
