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 1/2] i945/gma.c use latest linux code to calculate divisors.
-
-The code to compute n, m1, m2, p1 divisors is not correct in coreboot and
-on some targets hits a working mode at lower refresh rate, which is why
-display is working on some targets.
-This patch also fixes reference frequency.
-
-This patch reuses linux code to correctly compute divisors.
-
-The result is that some previously not working displays (Lenovo T60 with
-1024x786, 1400x1050, 2048x1536)
-
-TESTED on T60 with 1024x786.

-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".
