Subject: Re: pcmcia vs. MECR on pxa25x/sa1111

After 2.6.34 changes, __pxa2xx_drv_pcmcia_probe() was replaced by
sa1111_pcmcia_add(). That unfortunately means that configure_sockets()
is not called, leading to MECR not being set properly, leading to
strange crashes.

Tested on pxa255+sa1111, I do not have lubbock board nearby. Perhaps
cleaner solution exists?

Here's updated version. I'd prefer not to do too extensive changes as
I do not have lubbock nearby.
