Masayuki Ishikawa 12862c7b33 armv7-a: Fix comments on Cortex-A SGI
Summary:
- I noticed that Cortex-A SGI can be masked
- We thought the SGI is not maskable
- Although I can not remember how I tested it before
- It actually works as expected now
- Also, fixed the number of remaining bugs in TODO

Impact:
- No impact

Testing:
- Tested with sabre-6quad:smp (QEMU and dev board)
- Add the following code in up_idle() before calling asm("WFI");
+  if (0 != up_cpu_index())
+    {
+      up_irq_save();
+    }
- Run the hello app, you can see "Hello, World!!"
- But nsh will freeze soon because arm_pause_handler is not called.
