This new debugfs interface uses an IOCTL interface in order to pass
along state information like SRBM and GRBM bank switching. This
new interface also allows a full 32-bit MMIO address range which
the previous didn't. With this new design we have room to grow
the flexibility of the file as need be.
(v2): Move read/write to .read/.write, fix style, add comment
for IOCTL data structure
(v3): C style comments
(v4): use u32 in struct and remove offset variable
(v5): Drop flag clearing in op function, use 0xFFFFFFFF for broadcast
instead of 0x3FF, use mutex for op/ioctl.
