libmaple/pwr.h: Fix register bits (breaking change).
This is a backwards-incompatible change. It is necessary to fix an
error.
The register bit definitions are given as if they were masks, but
they're actually bit numbers. E.g., PWR_CR_DBP, which should be the
mask for DBP in the power control register PWR_CR, is actually the
number of the bit that should be masked.
Fix this by adding _BIT to the definitions and adding proper
masks. Also add a mask for the PVD level selection bits in
PWR_CSR. Don't add any mask values for particular voltages selected as
these are not portable.
