Subject: [PATCH v2] ALSA: hda/realtek: Add quirk for IPASON SmartBook S1

The internal speaker of the IPASON SmartBook S1 (an Emdoor ODM laptop)
stays silent under Linux, while the Bluetooth audio and the headset
output work fine.  The same machine plays sound under Windows with the
vendor driver, so the hardware and the amplifier are known good.

The BIOS reports the pin default of the actual internal speaker pin
(NID 0x1b) as 0x411111f0, i.e. the default association 0xf, which means
"unconnected".  The pin parser therefore drops that node already at the
pin-configuration time, hence no mixer control is ever created for it
and the pin is never driven, no matter how the output pin 0x14 is set
up.  Enabling 0x1b makes the speaker work immediately.

The existing ALC256_FIXUP_HONOR_MRB_XXX_M1020_AUDIO quirk makes the
speaker work, too, but it additionally rewrites the pins 0x14, 0x19 and
0x1a with Honor-specific values, which creates a bogus "Dock Mic" device
that does not exist on this hardware.  Add a minimal fixup that only
enables 0x1b as the internal speaker.  Touching 0x14 is not needed:
with the pin configuration overridden at runtime, both keeping its BIOS
value (0x90170110) and disabling it (0x411111f0) leave the speaker
working, so 0x1b alone decides the output.

  Codec:       Realtek ALC256 (0x10ec0256), SSID 0x2782:0x0206
  BIOS pincfg: 0x14 0x90170110  0x18 0x411111f0  0x19 0x02a19040
               0x1a 0x411111f0  0x1b 0x411111f0  0x1d 0x4067b945
               0x1e 0x411111f0  0x21 0x02214020

Tested on 7.2.0-1-MANJARO and 6.18.45-1-MANJARO, with both the SOF and
the legacy HDA driver paths.
