thermal/drivers/rzg2l: Fix comments

This patch replaces 'Capture times'->'Total number of ADC data samples' as
the former does not really explain much.

It also fixes the typo
 * caliberation->calibration

Lastly, as per the coding style /* should be on a separate line.
This patch fixes this issue.
