CAN_ESR2 register was having problems of havng the correct values when
the bus was busy (with 3 and more nods). The register bit fields were
incorrectly indicating that there is no free MB and would not updated
itself from this state which was causing the applications to freeze on
write. This change relies only on a software control which should avoid
the problems described above.

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.

This feature depends on frame pointer, "-fno-omit-frame-pointer" is mandatory
This feature can not be used in THUMB2 mode if you are using GCC toolchain,

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.

Add a driver for CorePWM block, which can be instantiated on PolarFire SOC FPGA
This supports 2 CorePWM blocks on the FPGA. One CorePWM block provides 8 PWM output signals
In AArch32, the frame pointer is stored in register R11 for ARM code or register R7 for Thumb code.
In AArch64, the frame pointer is stored in register X29.

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