The sa8775p-ride board development mostly happened back to year 2023,
and it hadn't got any major update since then, except Wasim's refactor[1]
last year which had no functional change for the board.

Propose to stop maintaining the board for reasons below.

- The Lemans development had moved to QCS9100/9075 EVK and Ride board
  for a long time.

- Qualcomm stopped maintaining Meta Build (NHLOS firmware) for this target
  years ago. There is not too much point to continuing maintaining the DT,
  as DT usually depends on NHLOS firmware.
