[PATCH net 2/6] net: dsa: vsc73xx: pass value in phy_write operation

[Pawel Dembicki <paweldembicki@gmail.com>]

In the 'vsc73xx_phy_write' function, the register value is missing,
and the phy write operation always sends zeros.

This commit passes the value variable into the proper register.

Fixes: 975ae7c69d51 ("net: phy: vitesse: Add support for VSC73xx")
