Not sure I understand your comment here. Without this
compatible in place I cannot see the 'drivers/amba/bus.c'
amba_match() function getting called which in turn will call the
amba_lookup() function,
thus invoking the probe function of the sp805_wdt driver.

Here is the comment on top of struct amba_bustype:

188 /*
189  * Primecells are part of the Advanced Microcontroller Bus Architecture,
190  * so we call the bus "amba".
191  */

Reference: http://lxr.free-electrons.com/source/drivers/amba/bus.c#L188

So, this should be  "arm,amba-bus", as used in other DTS as well like
ARM versatile
DTS:

  90         amba {
 91                 compatible = "arm,amba-bus";
 92                 #address-cells = <1>;
 93                 #size-cells = <1>;
 94                 ranges;
