linux: add missing 4.7.x options

[MilhouseVH]

These are required by the latest kernel bump, although I've been building fine without them (clean x2) some people need them. All defaults.

@lrusak: Virtual is a copy of Generic, not sure if you need anything different in Virtual.

CONFIG_PINCTRL_BAYTRAIL=y
(this becuase some Wifi are connected over SDIO/GPIO)
and
CONFIG_EFI_MIXED=y
for future support UEFI32 bootloader

[MilhouseVH]

@piotrasd: updated.

[piotrasd]

@MilhouseVH thx. i have ready version for UEFI32 but for now is ugly :/ i must little more polish

[stefansaraev]

in the past, CONFIG_EFI_MIXED was known to cause boot failures on some 64bit uefi configurations. no idea if this is still an issue (things may have changed in the meantime), and I dont remember the exact boards.

EDIT: at least zotac nano aq01 failed. I have one on the shelf. (assuming it still works after sitting idle for ... 2 years) I dont mind testing it for you if you share an image.

[piotrasd]

i checked few devices ... and was fine. We will see if someone raport after test @MilhouseVH nightly build. Without this is no possible boot normal LE version on devices with UEFI32

[MilhouseVH]

I've tested a Skylake NUC (UEFI) and Revo3700 (legacy BIOS), both booted OK.

@stefansaraev I'll get you an img.gz ASAP - will take a bout 30-40 minutes.

Thanks again.

[stefansaraev]

all good. boots fine on that stone old zotac box.

[MilhouseVH]

Thanks - probably best to let this bake for a couple of days and if no problems then merge.

[lrusak]

would be nice to get this merged ASAP, so if there are options you aren't sure about I would split them out into another PR. Otherwise jenkins and things will fail without default options set.

[MilhouseVH]

OK hang on.

[MilhouseVH]

Back to 100% defaults. I'll create another PR for the two new options.

[lrusak]

Yep works, thanks.
