net: phy: micrel: Advance register data pointer in write loop

Browse Source 
lanphy_write_reg_data() does not advance the data pointer while iterating
over the register table. As a result, it writes the first entry num times
and leaves the remaining errata registers unconfigured.

Single-entry tables are unaffected, but tables with multiple entries
leave every entry after the first unapplied.

Advance the data pointer after each successful write so every table entry
is applied in order.
