Summary:
- Remove -4/-8 offset coding in imx_irq.c and arm_vectors.S
- Instead, add SP adjustment after calling setirqstack/setfiqstack
- Fix off-by-one irq/fiq stack allocation in 8-byte aligned arch
- Fix comments on the user stack pointer in arm_vectors.S
- Also, fix up_dumpstate() to extract the user stack pointer
- NOTE: stack pointer alignment is 8-byte
Impact:
- Affects armv7-a with interrupt stack enabled
Testing:
- Tested with sabre-6quad:smp with QEMU
- Tested with sabre-6quad:nsh with QEMU

Summary:
- This commit fixes CPUx IDLE stack top for SMP
- Also removes SMP_STACK_TOP from smp.h
Impact:
- Affects armv7-a SMP only

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.

1.Get the stack pointer from sp instead of .Lstkinit's field
2.Make g_idle_topstack point to the end of the idle stack

arch/arm/src/tiva/cc13xx/cc13x0_rom.h,
arch/arm/src/tiva/cc13xx/cc13x2_cc26x2_v2_rom.h:
* Fix nxstyle errors; nxstyle was complaining about lack of a
space after comma because of the presence of line
continuation backslashes immediately after the comma.
Removed these backslashes as they are not necessary: these
lines are typedefs, not preprocessor defines.
arch/arm/src/tiva/cc13xx/cc13x2_v2_trim.c:
* Fix nxstyle errors.
* No functional changes; however modified one function,
trim_wakeup_fromshutdown(), to avoid blocks that existed
only to declare variables mid-function; nxstyle was
complaining about the positions of the opening and
closing braces of those blocks.
Summary:
- During Wi-Fi audio streaming test, I noticed data corruption in tcb
- Finally, I found an issue in IRQ request handing with IPI
- This commit fixes this issue
Impact:
- Affects SMP only
Testing:
- Tested with spresense:wifi_smp
