Input: ads7846 - fix gpiod allocation

Browse Source 
commit c9ccb88f534ca760d06590b67571c353a2f0cbcd upstream.

commit 767d83361a ("Input: ads7846 - Convert to use software nodes")

has simplified the code but accidentially converted a devm_gpiod_get()
to gpiod_get(). This leaves the gpio reserved on module remove and the
driver can no longer be loaded again.
