The name used in Tensilica support file core-isa.h for all vendors is
`XCHAL_NUM_INTLEVELS`.
Use a new name may be confused by newer porting xtensa arch.

The PRO CPU and APP CPU have different peripherals for GPIO interrupts.
Each CPU needs to allocate an interrupt and attach it to its GPIO
peripheral.

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.

Many duplicate code when more chips add-in,
follow arch/arm/include/irq.h method, use chip/irq.h instead.

Some toolchain such as xtensa-xcc is unrecognize with constraint letter 'I',
letter 'i' is more common in GNU assembler.

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

All modern desgin support stack pointer and it's also an
important information, so let's standardize this interface.

is enabled.
That region is technically part of the PRO CPU and we should be able to
allocate it early. However, QEMU uses a slightly different bootloader
image that uses the same part for both CPU. So, when APP CPU starts
during the SMP bring up it will corrupt some data.

Internal heap was occupying the region straight after .data up to
HEAP_REGION1. The issue with this is if static allocation is large,
we'll end up with too little memory left for the internal heap.
Moving it to the beginning of region 2 gives us more room to play with.
