[PATCH v2] staging: sm750fb: style fixes: align call and split chained assignment

[Cristian Del Gobbo <cristiandelgobbo87@gmail.com>]

- Drop previous change that made g_fbmode[] elements const (broke build).
- Align the continued arguments of sm750_hw_cursor_set_size() with the
  opening parenthesis.
- Replace a chained assignment of red/green/blue with a temporary
  variable to satisfy checkpatch and improve readability.

No functional change intended.
