The registers may be in window during interrupt.
Flush window stack to stack first.
And fix warning in build.

Up_getsp may be not inline in gcc, thus get the sp
is up_getsp function's sp, not the caller function.

functions will call esp32_txint again which leads to deadlock since
esp32_txint has already locked the spinlock.

This commit removes the initialization of the Wi-Fi partition
from the Wi-Fi board logic and moves it to the SPI Flash board code.
It creates 2 different partition (one for Wi-Fi and one for general
use).
It also allows these partitions to be mounted over several FSs.
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.

Matrix.
This allows manipulating interrupts from both CPUs. Internal interrupts
however, still need to be disabled/enabled by each CPU.

They do the same thing (manipulate interrupts) keeping them separated
was making things harder.

Allocating and attaching interrupts were both exported outside, however
these two move hand in hand and we don't have to expose these details.
Also, the parameters passed are saved and will be used to retrieve
information about the interrupt and the attached peripheral.

That function will have a parameter to decide whether to allocate a
level sensitive interrupt or an edge sensitive interrupt.
All the drivers are also updated with this API change.

are do not go through the regular process where we attache the CPU
interrupt to a peripheral and update our map, also, they are fixed and a
have reserved CPU interrupt, thus hard code their values at startup.

At this point we are in a critical section and have all the necessary
information to disable the interrupt properly (CPU, and CPU interrupt).
Leaving it to the drivers will complicate things as converting from IRQs
to CPU interrupts could be tricky in SMP mode.

This map also keeps track of the CPU that attached the IRQ. This will
be used to properly disable the interrupt in the correct CPU in SMP
mode.

ESP32 uses a different function to start the app CPU and no other xtensa
CPU uses this __cpu1_start function.

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.
