fsl-diu-fb: fix regression with uninitalized fb_info->mm_lock mutex

From: Krzysztof Helt <redacted>

Remove redundant call to the fsl_diu_set_par before the register_framebuffer().

This fixes a problem with uninitialized the fb_info->mm_lock mutex introduced 
by the commit 537a1bf059f " fbdev: add mutex for fb_mmap locking"

Signed-off-by: Krzysztof Helt <redacted>

---
If anybody could test this patch with the 2.6.30-rc2 kernel I am deeply grateful.

The fb_set_par() function is called after register_framebuffer() when fbcon
is taking over the console so a call just before the register_framebuffer()
is redundant.

Regards,
Krzysztof
