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)

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.

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'

[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.]
