[PATCH] drm/msm/disp: fix endian bug in debugfs code

[Dan Carpenter <dan.carpenter@oracle.com>]

The "vbif->features" is type unsigned long but the debugfs file
is treating it as a u32 type.  This will work in little endian
systems, but the correct thing is to change the debugfs to use
an unsigned long.

Fixes: 25fdd5933e4c ("drm/msm: Add SDM845 DPU support")

You might wonder why this code has so many casts.  It's required because
this data is const.  Which is fine because the file is read only.
