recipes-kernel/linux/linux-linaro-qcomlt-dev: use AUTOREV

This kernel recipe builds the QCLT integration branch which is not a
*relase* branch, but is regularly rebased. With a fixed SRCREV the
build will often break. Instead let's use AUTOREV. To avoid any
network issue during parsing we use AUTOREV only when the recipe is
selected, which most likely implies the user understands the risks and
the benefits!
