ASoC: Intel: bytcr_wm5102: Add BYT_WM5102_OUT_MAP quirk
Some x86 WM5102 designs don't use the SPK pins for speaker output instead they use the HPOUT2L + HPOUT2R for the speakers. Add an BYT_WM5102_OUT_MAP quirk mechanism to allow selecting between 2 output maps, one for the speakers on the SPK output pins and one for the speakers on the HPOUT2 pins. The new HPOUT2 map is enabled by default on CHT because this is used on the Lenovo Yoga Tab 3 YT3-X90 model which is the only Cherry Trail design currently supported. If different CHT designs turn up which need different output maps we can add DMI quirks to select a different map later. The userspace UCM profile also needs to know about this so setup a components string with this info too. While at it also drop the unused "Line Out" route.
