Add additional fdt fixup helper functions
Added the following fdt fixup helpers:
* do_fixup_by_prop{_u32} - Find matching nodes by property name/value
* do_fixup_by_compat{_u32} - Find matching nodes by compat
The _u32 variants work the same only the property they are setting
is know to be a 32-bit integer instead of a byte buffer.
