dartmonkey: Note for unused SLP_S4_L and SLP_SUS_L
These sleep lines were never used in code and have since been removed
from the reference schematic, but they are driven on nocturne.
This means that it would be bad if thee lines were ever accidentally
repurposed in the future.
Confirmed on A70 PVT/MP schematic.
