[v2] openocd: Enable linuxgpiod build option

Enable the linuxgpiod via PACKAGECONFIG to allow to use swd via
libgpiod.
linuxgpiod requires libgpiod 1.x, so it's required to add
PREFERRED_VERSION_libgpiod = "1.%".

@Bartosz it would be nice to be able to depend on libgpiod-1.x.
Guess the libraries could co-exist and then the libgpiod tools could be
from the 2.x.

Keep this comment but add:

RDEPENDS:${PN} += "libgpiod (<= 1.6.5)"

to this recipe to avoid build-time errors when the right version of
the library is not available.

Good idea.

Hi Bart,

I have tried:
RDEPENDS:${PN} += "libgpiod (<= 1.6.5)"
and/or
PACKAGECONFIG[linuxgpiod] = "--enable-linuxgpiod,--disable-linuxgpiod, libgpiod, libgpiod (<= 1.6.5)"

I still get buildtime errors :/
