[PATCH] drm/nouveau/fb: mark ramfuc_reg() noinline

[Paul Bolle <pebolle@tiscali.nl>]

Building ramnve0.o triggers a GCC warning on 32 bits x86:
    drivers/gpu/drm/nouveau/core/subdev/fb/ramnve0.c: In function 'nve0_ram_ctor':
    drivers/gpu/drm/nouveau/core/subdev/fb/ramnve0.c:1253:1: warning: the frame size of 1496 bytes is larger than 1024 bytes [-Wframe-larger-than=]

This warning is caused by ramfuc_reg(), which is inlined 74 times in
nve0_ram_ctor(). Mark it noinline to silence this warning.

Compile tested (on 32 bits x86) only. I've no Nvidia cards at hand, so I
can't really test it.

This assumes this function - a constructor, apparently - isn't called
often, so the overhead calling of 74 functions is acceptable. (The same
goes for the similar functions in [...]/ramnva3.c and in
[...]/ramnvc0.c, though these call ramfuc_reg() not quite as often.)
Perhaps there are other downsides to not inlining this function too. So
proper testing will probably be needed.
