[PATCH 13/40] mfd: ti_am335x_tscadc: Reword the comment explaining the dividers

[Miquel Raynal <miquel.raynal@bootlin.com>]

The comment misses the main information which is that we assume that a
sample takes 15 ADC clock cycles to be generated. Let's take the
occasion to rework a little bit this comment.
