Hi Russell,

thanks for the review.

Unfortunately, this function has a bug as it currently accesses EN0|EN1, 
but then this test is never true as EN1 is never being set in this 
driver. Intended was the access to PCMCIA_VS1|PCMCIA_VS2, but then 
get_cs3_shadow() was wrong and should now be simpad_get_cs3_ro().

I'll fix this and hope someone can test this as I don't have a Simpad 
with PCMCIA.

Thanks,
Jochen
