pinctrl: baytrail: Rectify debounce support (part 2)

Browse source 
[ Upstream commit 827e1579e1 ]

The commit 04ff5a095d ("pinctrl: baytrail: Rectify debounce support")
almost fixes the logic of debuonce but missed couple of things, i.e.
typo in mask when disabling debounce and lack of enabling it back.

This patch addresses above issues.
