ALSA: add Intel HDMI LPE audio driver for BYT/CHT-T On Baytrail and Cherrytrail, HDaudio may be fused out or disabled by the BIOS. This driver enables an alternate path to the i915 display registers and DMA. Although there is no hardware path between i915 display and LPE/SST audio clusters, this HDMI capability is referred to in the documentation as "HDMI LPE Audio" so we keep the name for consistency. There is no hardware path or control dependencies with the LPE/SST DSP functionality. The hdmi-lpe-audio driver will be probed when the i915 driver creates a child platform device. Since this driver is neither SoC nor PCI, a new x86 folder is added Additional indirections in the code will be cleaned up in the next series to aid smoother DP integration Signed-off-by: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com> Signed-off-by: Jerome Anand <jerome.anand@intel.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>

menuconfig SND_X86
ALSA: x86: Make CONFIG_SND_X86 bool CONFIG_SND_X86 is a menu config to filter only for x86-specific drivers in its sub-menu, and this doesn't have to be tristate but rather it should be a bool. Also, like other sub-menu configs, it's more user-friendly to be default=y; it's merely a menu config and the actual drivers are configured in the sub-menu, after all.
