librecore integration preparation: drop post-20160907 coreboot patches

Most of them don't apply, and they are merged upstream in librecore already.

Librecore is becoming Libreboot's main firmware upstream.

-Subject: [PATCH] lenovo/t60: add hda_verb.c
-
-This creates a config for the Lenovo T60 sound card based
-on values taken from vendor bios
-(in /sys/class/sound/hwC0D0/init_pin_configs on linux 3.16).
-The sound card configuration on the vendor bios is the same
-as the one on the Lenovo x60.
-
-It improves the default behavior of the sound card:
-- internal microphone is chosen by default
-- when jack is inserted it is chosen instead of internal speaker

-Subject: [PATCH 2/2] i945/gma.c: add native VGA init
-
-This reuses the Intel Pineview native graphic initialization
-to have output on the VGA connector of i945 devices.
-
-The behavior is the same as with the vendor VBIOS BLOB.
-It uses the external VGA display if it is connected.

-Subject: [PATCH] i945/gma.c: generate fake VBT
-
-This generates a fake VBT for the Intel i945 graphic device.
-i945 supports both the mobile chipset 945gm (calistoga)
-and the desktop chipset 945gc (lakeport),
-which is why a VBT with a different id string
-needs to be created for each target.
-
-The VBT id string is obtained from the vbios blob in the following way:
-"strings vbios.bin | grep VBT".
