dt-bindings: display: himax-hx8394: Add Huiling hl055fhav028c

Add compatible string for the Huiling hl055fhav028c. This panel is
based on the Himax HX8399C display controller which is extremely
similar to the existing HX8394. Add a new constant for
himax,hx8399c for this new display controller as well.
