fbc1da98b7 xtensa: use swint to swith context
Reason for use sw-interrupt as syscall interrupt:
The xtensa `syscall` instruction can cause SYSCALL interrupt.
But SYSCALL interrupt is same interrupt level with level-one
interrupt.
Nuttx swint can enter `enter_critical_section` and gerenate
interrupt.

f5d180bbdf xtensa: spit up_irq_disable and up_irq_save INTLEVEL MARCO
For up_irq_disable, use XCHAL_EXCM_LEVEL
For up_irq_save,  use XCHAL_IRQ_LEVEL.
Then we can use svcall in enter_crritical_section.

7b00c8bdb8 arch:xtensa: modify svcall to swint
Reason: xtensa svcall only have level-1 interrupt level.
Sush do not generate interrupt when up_irq_save.
Software int can generate interrupt when up_irq_save.

f826e053ae arch/xtensa/esp32: Remove the QEMU special case when initializing the
heap.

QEMU had a different ROM image that used the regions of PRO CPU for both
CPUs.  This was causing crashes when running SMP mode as the heap was
being corrupted when the APP CPU starts.

QEMU is now loading the same image as the hardware chip and thus this
special case doesn't exist anymore.

e333733053 xtensa:coproc: fix XTENSA_CP_ALLSET error in some case
Consider follow coprocessor configuration case:

\#define XCHAL_CP_NUM                    1       /* number of coprocessors */
\#define XCHAL_CP_MAX                    2       /* max CP ID + 1 (0 if none) */
\#define XCHAL_CP_MASK                   0x02    /* bitmask of all CPs by ID */
\#define XCHAL_CP_PORT_MASK              0x00    /* bitmask of only port CPs */
\
\#define XCHAL_CP1_NAME                  "AudioEngineLX"
\#define XCHAL_CP1_IDENT                 AudioEngineLX
\#define XCHAL_CP1_SA_SIZE               208     /* size of state save area */
\#define XCHAL_CP1_SA_ALIGN              8       /* min alignment of save area */
\#define XCHAL_CP_ID_AUDIOENGINELX       1       /* coprocessor ID (0..7) */

In this case, XTENSA_CP_ALLSET is 0x1, but valid coprocessors
bitmap is 0x2, use marco XCHAL_CP_MASK instead, it is bitmap of all
vaild coprocs.

2d016f8d21 arch: xtensa: Fix the PS register handling
Summary:
- I noticed that DEBUGASSERT sometimes happens in nxsem_wait()
  when testing Wi-Fi with esp32-devkitc:wsifi_smp
- The call stack was not from an interrupt handler and actually
  g_current_regs[] were correct, even though asserted with
  (up_interrupt_handler() == false)
- Finally, I found that we need to call rsync after we set
  a new value to the PS register which is described in the
  Xtensa document.
- This commit fixes this issue

Impact:
- All xtensa architectures

Testing:
- Tested with esp32-devkitc:wifi_smp and esp32-devkitc:wifi
