03ee513bda linux: fix fbtft kernel extension
Fixes fbtft kernel extension bug reported by Richard Fergusson ([1]):

drivers/video/Kconfig:2525: can't open file
"drivers/video/fbdev/fbtft/Kconfig"

Fix: write the right fbtft/KConfig path to video/Kconfig or
video/fbdev/Kconfig (instead of hard coded one)

53785a2c77 linux: fix extensions
Since the move to the kconfig-package infra, linux extensions are
broken.

In our linux package, extensions are applied as pre-patch hooks.

Before the kconfig-package infra, we had custom rules for the
linux-*config targets, which were of the form:

    linux-menuconfig: linux-configure
        $(MAKE) -C $(LINUX_DIR) menuconfig

This caused the linux tree to be fully configured before running the
configurators, and thus linux dependencies were entirely fullfilled, and
extensions were properly applied.

Since we migrated (in dff25ea), the kconfig-package infra introduces a
(hidden, internal) intermediate step 'kconfig-fixup' and decorelates the
kconfig-part of the configuration from the actual package-part of the
configuration:

    linux-configure -------> kconfig-fixup --> .config --> $(LINUX_CONFIG_FILE)
                        /
    linux-menuconfig --'

As thus, this (very useful!) use-case breaks (starting from a clean
Buildroot tree):

    make menuconfig
        -> enable a kernel and at least one extension
        -> save and exit
    make linux-menuconfig
        -> extensions are not available

Fix that by using the newly-introduced patch-dependencies, so that
extensions are available before we try to patch the linux kernel.

9b2bbe3422 linux: add fbtft kernel extension
Tested with RaspberryPi B+ and PiTFT Mini Kit - 320x240 2.8" TFT
(see [1] and [2]) and the following target configuration changes:
- cmdline.txt: add 'fbcon=map:10 fbcon=font:VGA8x8'
- add /etc/modules-load.d/fbtft.conf with 'fbtft_device'
- add /etc/modprobe.d/00-fbtft.conf with 'options fbtft_device name=adafruit28 rotate=90 gpios=dc:25'

[2] http://h65951.serverkompetenz.net/PeterSeiderer/upload/PiTFT_2_8_ct/Image9897.jpg

[Thomas:
  - Rename prompt of the Linux extension to "FB TFT drivers"
  - Remove the full name of the kernel config options in the help
    text. Giving their CONFIG_<foo> name is enough.
  - Remove the mention of CONFIG_SPI_BCM2708, since this makes the
    description RaspberryPi specific, while these drivers can work
    with any SPI controller.
  - Refactor the code in linux-ext-fbtft.mk to avoid duplication
    between the < 3.15 and >= 3.15 cases.
  - Make the fbtft package a promptless package, since there is no
    point in selecting only this package, without the kernel
    extension.
  - Change the license to GPLv2, since it's kernel code.]
