bcd2bin(0x0A) happily returns 10, despite this being an invalid BCD value. RTC drivers converting possibly corrupted BCD timestamps might want to validate their input before calling bcd2bin(). Provide a macro to do so. Unlike bcd2bin and bin2bcd, out-of-line versions are not implemented. Should the macro experience enough use, this can be retrofitted.
