kernel: modules: package Marvell gigE PHY driver

Some copper SFP modules come with Marvell's 88E1xxx PHY and need this
module to function. Package it, so users can easily install this PHY
driver and use e.g. FINISAR CORP. FCLF-8521-3-HC SFP.

Without marvell PHY driver:
sfp sfp2: module FINISAR CORP.    FCLF-8521-3-HC   rev A    sn XXXXXXX          dc XXXXXX
mt7530 mdio-bus:1f sfp2: validation with support 0000000,00000000,00000000 failed: -22
sfp sfp2: sfp_add_phy failed: -22

With marvell PHY driver:
sfp sfp2: module FINISAR CORP.    FCLF-8521-3-HC   rev A    sn XXXXXXX          dc XXXXXX
mt7530 mdio-bus:1f sfp2: switched to inband/sgmii link mode
mt7530 mdio-bus:1f sfp2: PHY [i2c:sfp2:16] driver [Marvell 88E1111] (irq=POLL)
mt7530 mdio-bus:1f sfp2: Link is Up - 1Gbps/Full - flow control rx/tx
