Subject: [PATCH v2] spi: spidev: Add compatible for LWE's btt device

The Liebherr's BTT devices are using spidev to communicate via
SPI to monitoring devices. Extend compatibles to allow proper
DTS description.

Changes for v2:
- Use 'lwn' vendor prefix instead of 'lwe' (as the former one is already
  well used in Linux sources).
