To simplify this process, we introduce a single macro for configuring the digital noise filter. This patch removes the PIN_CFG_FILNUM and PIN_CFG_FILCLKSEL configuration macros and renames PIN_CFG_FILONOFF to PIN_CFG_NF.

Previously, this call was redundantly made in each case of the switch statement.
