lemans-auto.dtsi maintains an old "automotive" memory map to support
legacy use cases, which stopped being supported by Qualcomm META build
2 years ago. So there is very unlikely anyone still running it. Remove
the file and update sa8775p-ride boards to include lemans.dtsi directly.

So because RIDE is the "automotive development" platform, do we have
anyone running the (effectively) IoT firmware on it, or should the
boards be removed in general?

I doubt that one can run IoT firmware, i.e. QCS9100 version, directly
on SA8775P board, even though both are non-gearvm variant.  At least,
SA8775P and QCS9100 have different SoC ID.

I'm all for removing sa8775p-ride boards if they are completely obsolete
and superseded by qcs9100-ride. For the record, I haven't seen sa8775p-ride
board anywhere these days.
