phy: marvell: add missing speed during info prints

In get_speed_string() we have an array (speed_strings[])
which includes all possible speed strings.
This array size and content must be aligned to the speed
defines in comphy_data.h.

This patch adds missing 5.125G speed, aligns speed_strings[]
and fixes incorrect printing when speed > 5.0G.
