[][kernel][mt7988][i2.5gphy][net: phy: Fix RTL8156B 100Mbps EEE link down issue by setting lpi_SigEnLoThresh100 to 0]

[Description]
Fix RTL8156B 100Mbps EEE link down issue by setting lpi_SigEnLoThresh100
to 0. This fix will freeze parts of DSP states.

Without this patch, if testing internal 2.5gphy with RTL8156B cards,
you may suffer from link down during 100Mbps EEE.
