mbxfb: add more registers to debugfs
PATCH 3/5 mbxfb: add more registers to debugfs
This patch fixes debugfs for mbxfb and adds some missing registers.
The way registers were read was out of sync with the rest of the driver (direct access instead of using readl())
sdram controller registers are now accessible in the sdram/ subdirectory and some other registers are grouped in the misc/ subdirectory.
