Karthikeyan Ramasubramanian 0b4f49c792 util/spd_tools/spd_gen/lp5: Remove maxSpeed for Sabrina
Firmware component that does memory training already limits the memory
controller to train at 5500 Mbps for all memory parts in Sabrina. Hence
removing this interim SPD change to limit the speed.

BUG=b:238074863
TEST=Build and boot to OS in Skyrim.
