ALSA: hda/ca0132: Set HP/Speaker auto-detect default from headphone pin verb
HP/Speaker auto-detect (VNID_HP_ASEL) has been off by default for every
CA0132 device since the driver was added in 2012. vnode_lswitch is
always initialized to 0 in ca0132_init_chip(), and no quirk or other
code path enables it. As a result, headphone jack detection works only
after the user manually turns on "HP/Speaker Auto Detect" in alsamixer,
which is not obvious on laptops with combo jacks (e.g. Google Link,
Alienware).
Change the default to follow the headphone pin config: if the pin verb
has presence detect enabled (no AC_DEFCFG_MISC_NO_PRESENCE) and the
codec supports it (AC_PINCAP_PRES_DETECT), enable HP_ASEL by default.
This lets firmware (coreboot, UEFI, etc.) express whether the headphone
jack supports insertion detection. Devices with combo jacks can default
to auto-detect; devices with fixed/no jack leave it off.
