We need this fix to enable h264 decoding on g4x platform.
There are two patches to fix the problem.
1. merge ring irq put-get pair into bsd_ring irq put-get pair
2. add conditional judgment about dev version to use different interrupt control interfaces.
As the patches show, g4x has a different interrupt control interface. So an if-else statement
is needed. And make all differences in a put-get pair is reasonable, since the differences are neither
so many to use another date structure nor so few to present by an argument.
