altera_epcq_controller_mod.c: Fix faulty read/write end address check.

Browse Source 
In the Flash info structure, the field containing the end address of
the Flash storage is documented to be non-inclusive.

However, when this field is compared to the end address of a read or
write, which is also non-inclusive, it is considered an error that
these two values match, which is incorrect, as this would error out
on an attempt to fully read/write the last page.

Fix this by simply changing the >= comparison into a > one.
