stm32f3: adc: rationalize Sampling Time definitions.

Browse Source 
There are as many SMPRx registers are needed for channels supported, and on all
other families, the field definitions are just ADC_SMPR_SMP_XXX.  For
consistency, and to avoid any confusion or duplication, use the same style here
too.  Drop silly unused per channel definitions that have no purpose.
