Adding the CONFIG_ARCH_PERF_EVENTS configuration to enable
hardware performance counting，solve the problem that some platform
hardware counting support is not perfect, you can choose to use
software interface.
This is configured using CONFIG_ARCH_PERF_EVENTS, so weak_functions
are removed to prevent confusion
To use hardware performance counting, must:
1. Configure CONFIG_ARCH_PERF_EVENTS, default selection
2. Call up_perf_init for initialization

The first time interrupt nesting occurs between REE and TEE,
CURRENT_REGS needs to be set.
If TEE nesting REE breaks, then EXC_RETURN.S=0,EXC_RETURN.ES=1;
Conversely, EXC_RETURN.S=1,EXC_RETURN.ES=0;
Interrupt nesting between TEE and REE can be determined based
on the S and ES bits of EXC_RETURN.
Only once nesting between TEE and REE is supported, and cyclic
nesting between TEE and REE is not supported.

1、The process stack supports interrupt nesting, Execute in MSP;
2、The interrupt stack supports interrupt nesting;
The thread mode use PSP, and the handle mode use MSP;
3、Adjust arm_doirq、exception_common implementation to meet interrupt nesting
4、Adjust the conditions for returning MSP and PSP;
5、remove setintstack;

For TEE & REE, securefault & busfault are not banked, so the faults can
only forword to TEE/REE.
But how to crash dump the other core which not handled faults ?
Here we provide a way to resolve this problem:
1. Set the securefault & busfault to TEE
2. busfault happend from TEE, then directly dump TEE
3. busfault happend from REE, then generate nonsecurefault
4. Back to REE, and dump

FlexCAN before used interrupts to process incoming frames.
This patch adds a HPWORK workqueue to process incoming frames in the workqueue
context instead. Also renamed mbi to txmb for better readability.
* Error handling for abnormal interrupts and DMA errors is now
enabled for all builds, regardless of any DEBUG configuration.
* Error handling resets the MAC for the specific errors that
may halt the Ethernet operation, instead of everything as it
was before.
When supporting high-priority interrupts, updating the
g_running_tasks within a high-priority interrupt may be
cause problems. The g_running_tasks should only be updated
when it is determined that a task context switch has occurred.
