pinctrl: intel: Retain HOSTSW_OWN for requested gpio pin The touchpad of the ASUS laptops E403NA, X540NA, X541NA are not responsive after suspend/resume. The following error message shows after resume. i2c_hid i2c-ELAN1200:00: failed to reset device. On these laptops, the touchpad interrupt is connected via a GPIO pin which is controlled by Intel pinctrl. After system resumes, the GPIO is in ACPI mode and no longer works as an IRQ. This commit saves the HOSTSW_OWN value during suspend, make sure the HOSTSW_OWN mode remains the same after resume.
