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.
