arch/arm/src/tiva/hardware/cc13x2_cc26x2/cc13x2_cc26x2_adi3_refsys.h:
* Fix syntax error. The define ADI3_REFSYS_DCDCCTL0_VDDR_TRIM_MIN
had an unintentional comment closing "*/" in the middle of its
name.
This separation allows to interact with the watchdog from OS code,
for example initiating the watchdog very early on boot. Moreover,
these changes make the lower-half driver support an already running
watchdog, which may happen if there's a bootloader which already
started it.

Summary:
- This commit fixes CPUx IDLE stack top for SMP
- Also removes SMP_STACK_TOP from smp.h

There is a good case on sim platform:
When we input some cmd and click enter key to start application in terminal,
this context will change to application from IDLE loop. Althrough entey key '\r'
has been received to recv buffer and complete post semaphore of reader, but
pollnotify may not be called because context change. So when application run
poll function, because no events happend and poll enter wait, context will
again change to IDLE loop, this pollnotify of IDLE loop will run to send poll
events, poll function of applicaton will wake up. It's wrong!

Summary:
- Modify arm_intstack_base() to return "top" of the IRQ stack for the current CPU
- This change fixes IRQ stack dump information for ARM SMP
- Add arm_intstack_alloc() to return "bottom" of the IRQ stack for the current CPU
- Also, these functions are now implemented in xxx_irq.c (imx/cxd56/lc823450)
- up_color_intstack() and up_check_intstack() now call arm_intstack_alloc()
- These semantics are now consistent with non-SMP case
- up_color_intstack() now initializes whole IRQ stack region for SMP
- Adjust IRQ stack top address for each CPU (e.g. -8)
- Fix setintstack to handle in case of NCPUS=1 (cxd56, lc823450)
- Adjust INTSTACK_SIZE to 8 bytes alignment (cxd56, lc823450)
- Refactor setintstack for lc823450
- Remove old IRQ stack coloring code from up_irqinitialize() (lc823450)
- Introduce g_cpu_intstack_top for lc823450
- Refactor header files
Impact:
- Affects imx6/cxd56xx/lc823450 SMP with interrupt stack enabled
Testing:
- Tested with sabre-6quad:smp (with QEMU, NCPUS=1 and 4)
- Tested with spresense:wifi_smp (NCPUS=1 and 2)
- Tested with lc823450-xgevk:rndis (NCPUS=1 and 2)

cfsetispeed() now stores baud rate to c_cflag member of
struct termios, so it must not be overridden later on.
