[PATCH] UV: redundant creation of sgi_uv

[Cliff Wickman <cpw@sgi.com>]

From: Cliff Wickman <cpw@sgi.com>

There is a collision between two UV functions:
  both uv_ptc_init() and gru_proc_init() try to make /proc/sgi_uv

So move it's creation to a single place: uv_system_init()

Diffed against 2.6.28-rc3
