Input: cyttsp5 - ensure minimum reset pulse width

commit c6cb8bf7 upstream.

The current reset pulse width is measured to be 5us on a
Renesas RZ/G2L SOM. The manufacturer's minimum reset pulse width is
specified as 10us.

Extend reset pulse width to make sure it is long enough on all platforms.

Also reword confusing comments about reset pin assertion.
