Provide `up_copy_section` function that enables copying data using
the data bus. If the memory destination address is accessible
through the instruction bus, the data is copied using the
correspondent address accessible through the data bus.
rename _rdtsc macro to rdtsc to avoid conflict with external code
rename rdtsc macro to rdtscp to be the same as asm instruction used

The buffer initialization function (`i2s_buf_initialize`) calls
`i2s_buf_free`, which performs buffer initialization within a
critical section (`spin_lock_irqsave`). If this function is called
under the same critical section (same spinlock), initialization
will hang.
This change implements a driver for the two watchdog timers on the BL808, and enables it as part of the timer config. The driver is based on the GP timer driver.
arch/xtensa: add support for capture driver on ESP32 and ESP32|S3|
Squashed:
Initial settings for MCPWM Capture on board level
Created lower half files - compilation ok
Using capture debug features. Simple example on fops works
Successful duty and freq calculation
Documentation update
Fixed and added interupt capabilities for all 3 capture channels
Cleaned defconfig
Renamed macros, added S3 options and moved arch source to common dir
Added support for ESP32S3
Added capture example to defconfig and renamed
Basic bring up ready. New Kconfig options for motor.
Good motor registration
Working on enabling pwm generators
Working on enabling pwm generators
Added fops functions
Success on PWM 50%
stable pwm operation for bdc
Added loopback option for testing
Improved rules on fsm
Working motor direction control
Testing new ISR for fault handling
Issues on fault ISR
Removed fault implementation (not working)
Added support for esp32s3
Documentation improvements
Added default motor spin direction
Added parameter change while running
Review fixes

when the thread to backtrace is exiting, get_tcb and up_backtrace in
different critical section may cause try to dump invalid pointer, have
to ensure the nxsched_get_tcb and up_backtrace inside same critical
section procedure.

This fixes the always zero time in NuttSBI case as the `error` field
contains the correct timestamp. This in turn also fixes the block of
`up_udelay()` which further leads to boot failure of `canmv230:master`
config.

Correctly releasing channels after using QSPI is crucial
to prevent issues caused by multiple requests that may lead
to DMA channel resource conflicts.
The common `up_allocate_heap` is a strong symbol, which leads to
error when building with CONFIG_DEBUG_LINK_WHOLE_ARCHIVE. Make
`up_allocate_heap` weak function to mitigate this problem.

This PR configures the BL808 and SG2000 MMU (inside T-Head C906) to cache the the Kernel Text, Data and Heap. We set the MMU Flags (Shareable, Bufferable and Cacheable) as explained in this article: https://lupyuen.github.io/articles/plic3#appendix-mmu-caching-for-t-head-c906
This PR fixes the Slow Memory Access for NuttX Kernel in BL808 and SG2000: https://github.com/apache/nuttx/issues/12696
In the next PR, we will fix the Slow Memory Access for NuttX Apps, by caching the User Text and Data.

This fixes `tp` value of forked child in PROTECTED build to support
