Blackfin: BF51x/BF52x: support GPIO Hysteresis/Schmitt Trigger options
Newer parts have optional Hysteresis/Schmitt Trigger options to help with dirty signals. So add some kconfig options for tuning this and enable it by default for people. Signed-off-by: Michael Hennerich <michael.hennerich@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

+ The ADSP-BF52x allows to control input hysteresis for Port F,

+ The Schmitt trigger enables can be set only for pin groups.
