[][kernel][mt7988][dts][Add los-gpios definition for SFP+]

[Description]
Add los-gpios definition for SFP+.

SoC default output HIGH to LOS of SFP cage, this behavior might casue
SFP devices report incorrect to the kernel.
Therefore, we need to change this Pin to GPIO input mode.

If without this patch, kernel might read the incorrect LOS status
from SFP devices.
