Subject: [PATCH 16/17] fbcon: initialize blink interval before calling
 fb_set_par

Since commit 27a4c827c34ac4256a190cc9d24607f953c1c459
    fbcon: use the cursor blink interval provided by vt

a PPC64LE kernel fails to boot when fbcon_add_cursor_timer uses an
uninitialized ops->cur_blink_jiffies. Prevent by initializing
in fbcon_init before the call to info->fbops->fb_set_par.
