stmhal: Allow to set bits resolution for DAC; 8 is default, can have 12.
This patch allows to configure the DAC resolution in the constructor and
in the init function, eg:
dac = DAC(1, bits=12).
The default resolution is 8 bits for backwards compatibility. The bits
sets the maximum value accepted by write and write_timed methods, being
2**bits - 1.
When using write_timed with 12-bit resolution, the input buffer is
treated as an unsigned half-word array, typecode 'H'.
See PR #1130 for discussion.
