Currently, the compatible string used for Liebherr's BK4 external SPI
controller device is "lwn,bk4", which is the same as the board compatible
string documented at fsl.yaml.

This causes several dt-schema warnings:

make dtbs_check DT_SCHEMA_FILES=fsl.yaml
...

['lwn,bk4'] is too short
'lwn,bk4' is not one of ['tq,imx8dxp-tqma8xdp-mba8xx']
'lwn,bk4' is not one of ['tq,imx8qxp-tqma8xqp-mba8xx']
'lwn,bk4' is not one of ['armadeus,imx1-apf9328', 'fsl,imx1ads']
...

Add a more specific "lwn,bk4-spi" compatible string entry for this
device to fix the problem.

The original "lwn,bk4" is kept to keep compatibility with old DTBs.
