bindings: input: qcom-hv-haptics: Change to use 8-bit FIFO data 

Hardware with revision 2 is changed to use 8-bit FIFO memory while
revision 1 is using 9-bit FIFO memory. To unify the data assignment
from devicetree, change to use 8-bit data for "qcom,wf-fifo-data"
property. Software can expand the 8-bit data to 9-bit for V1
hardware accordingly.
