fdt: Add a function to count strings

Browse source 
Given a device tree node and a property name, the fdt_stringlist_count()
function counts the number of strings found in the property value.

This also adds a new error code, FDT_ERR_BADVALUE, that the function
returns when it encounters a non-NUL-terminated string list.
