TPDM serves as data collection component for various dataset types.
DSB(Discrete Single Bit) is one of the dataset types. DSB subunit
can be enabled for data collection by writing 1 to the first bit of
DSB_CR register. This change is to add enable/disable function for
DSB dataset by writing DSB_CR register.

The patch looks good to me, except for some minor comment below.

Missed this. The general convention is to use:

__tpdm_disable()
__tpdm_enable();

So, please switch to the names above.
