V4L/DVB (7219): zoran: Fix namespace conflicts with Zoran 'GPIO_MAX' enum

Thanks to Martin Michlmayr <tbm@cyrius.com> for reporting this issue:

The zoran driver fails to compile on the ARM Orion platform with:

In file included from drivers/media/video/zoran_procfs.c:50:
drivers/media/video/zoran.h:232: error: expected identifier before numeric
constant

The reason is that drivers/media/video/zoran.h defines an enum with
GPIO_MAX in it, but Orion contains a #define GPIO_MAX 32 in
include/asm-arm/arch-orion/orion.h
