ARM: rpi: parse useful data from vc fdt
Videocore first-stage loader on rpi passes us many useful information
inside the vc fdt, including the real value of PM_RSTS register, not
easily available by other means and which we can use to determine
the reset cause.
Also make the relevant funtions just print error/warning and continue
in case of some errors, since the fdt from vc is now optional for
barebox's basic function.
