pinctrl: intel: Add ~4k bias support
All versions that have 20k and 5k resistance, i.e. all that the driver supports, may support ~4k when the above mentioned are connected in parallel. Add such a support. Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Acked-by: Mika Westerberg <mika.westerberg@linux.intel.com>
