pcmcia: limit pxa2xx_trizeps4 subdriver to trizeps4 platform
pxa2xx_trizeps4 tries to register pxa2xx-pcmcia device not checking whether machine is really trizeps4, thus messing multi-machine kernels. Fix it up. Signed-off-by: Dmitry Eremin-Solenikov <dbaryshkov@gmail.com> Signed-off-by: Eric Miao <eric.y.miao@gmail.com>
