The various register access wrappers in nouveau_hw.h are so noisy when
drm.debug > 0, that some of them can overflow the kernel message buffer.
Add nouveau.ko parameter 'reg_debug', a bitmask that enables each of the
wrapper debug messages individually. By default, nothing is printed.

To: nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW
Several register read wrappers in nouveau_hw.h did the MMIO read twice,
but only if debugging was enabled. Fix these to first read the register,
then debug-print the value, instead of reading it once for debug and
once for real.
Also, fix some style issues with long lines around the fixes.

These functions were effectively nv_rd32 and nv_wr32 with a debug print,
and they were never used. Remove them.

The size parameter is usually unsigned, but here it was signed. Change
'int' to 'uint32_t' and propagate the signedness fixes to all callers.
Fixes the sparse warning: nouveau_object.c:254:61: warning: incorrect
type in argument 3 (different signedness).
