plat/stm32: Implement fdt_read_uint32_default() as a wrapper
The STM32 platform code uses its own set of FDT helper functions,
although some of them are fairly generic.
Remove the implementation of fdt_read_uint32_default() and implement it
on top of the newly introduced fdt_read_uint32() function, then convert
all users over.
This also fixes two callers, which were slightly abusing the "default"
semantic.
