rust: io: fix example in register! macro

Browse Source 
In this example, an u32 register is split in two u8 in big-endian order,
but the high byte is actually defined as taking nine bits instead of
eight.

This is completely inconsequential, as I expect most users will just
copy the bit ranges from their datasheets, but it doesn’t hurt to fix
that typo.
