fix(drivers/marvell/comphy-3700): fix SerDes frequency register value name
Constants SD_SPEED_1_25_G and SD_SPEED_2_5_G refer to SerDes frequency,
which is 1.25x that of data rate, since 1000base-x and 2500base-x use
the 8b/10b encoding:
mode frequency data rate
1000base-x 1.25 GHz 1 Gbps
2500base-x 3.125 GHz 2.5 Gbps
But the first constant refers to the frequency, while the second to the
data rate, which does not make sense.
Since the values in the specification refer to frequency, change the
name of the constant SD_SPEED_2_5_G to SD_SPEED_3_125_G to also refer to
the frequency, as SD_SPEED_1_25_G does.
