native: enable GPIOLIB + Intel pinctrl for MAX98360A amp enable

Audio card now registers (sof-rt5682 + HP-Drawman-rev13-Drawcia) and
ac-native opens hw:0,0 at 48000Hz after the I2C_DESIGNWARE fix — but
the speakers are silent because the MAX98360A amp's SD_MODE enable is
a GPIO, and the kernel had no GPIO framework at all. Without GPIOLIB
the amp driver still loads but it never gets to toggle the pin high,
so the amp stays in power-down mode and nothing reaches the drivers.

Enable GPIOLIB + Intel pinctrl for every Intel generation we might
boot on (Bay/Cherry/Sunrise/Gemini/Elkhart/Jasper/Tiger/Alder/Meteor/
Lunar/Panther). Same story applies to touchpads, rfkill switches,
EC-controlled keyboard backlights, etc. — GPIOs are the connective
tissue of every modern x86 laptop.
