Add the DT node for the VBATTB IP along with DT bindings for the clock
it provides.

Changes in v5:
- dropped the status = "disabled"; for the vbattb-xtal node
Changes in v4:
- used clock-controller for the vbattb node name
- move the node near scif0 for ordering
- set the vbattb_xtal status as disabled to avoid having it exported
in linux with frequency = 0 in boards that don't use it
- collected tags
Changes in v3:
- dropped the child nodes of vbattb; along with this dropped ranges,
interrupt-names, #address-cells, #size-cells
- added vbattb_xtal as input clock for vbattb
Changes in v2:
- update compatibles
- updated clocks and clock-names for clock-controller node
- removed the power domain from the clock-controller as this is
controlled by parent node in v2
