drm/omap: dsi: Fix excessive stack usage

Browse source

[ Upstream commit cfca78971b ]

dsi_dump_dsi_irqs(), a function used for debugfs prints, has a large
struct in its frame, which can result in:

drivers/gpu/drm/omapdrm/dss/dsi.c:1126:1: warning: the frame size of 1060 bytes is larger than 1024 bytes [-Wframe-larger-than=]

As the performance of the function is of no concern, let's allocate the
struct with kmalloc instead.

Compile-tested only.
