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

Increase max V. Backporch value from 63 to 236
...
This change allows highly letterboxed content (e.g. the PSP's 480x272
picture in a 720x480 frame) to be "zoomed" to a full screen picture by
treating the letterbox as horizontal and vertical backporch.
