This commit allows placing .bss data into the external PSRAM.
Previously, the PSRAM was fully allocated to the heap memory only
and now part of it can be used to allocate .bss data freeing the
internal memory.
on ESP32, cpuint was allocated when register wdt handler, but not
deallocated when unregister, which cause debug assert when checking
`DEBUGASSERT((*freeints & bitmask) == 0)`, so set cpuint to initial value
after deallocate.
The same issue on ESP32s3 has been fixed by PR#15433
Update the wireless symbols from ESP32S3_* to ESPRESSIF_* for using common layer.
Remove ESP32S3 specific WiFi files and edit build system to use common layer.
Instead of enabling an interrupt on the calling hart, enable it on every
hart. This should balance the interrupt load some, especially in cases
where the interrupt source is enabled only once (which will almost
certainly happen on CPU 0 only).

This commit adds support to TIOCGICOUNT for STM32, this way a
userspace application can collect information about UART errors.

Fixes bug where stm32_phyinit will succeed even when no PHY is connected. This is because there is no check that a PHY is actually communicating and returning data.

Due to interrupt latencies the i2c transfer done interrupt can get
deferred by a few hunder microseconds. This makes the i2c transfer timeout
way too early, even though the i2c IP block is already done.
Fix this by adding a significant amount of margin (1ms) to the timeout
value.
This removes several error conditions that can be present after a failed
i2c transaction. The most important of them is the priv->sem_isr semaphore
which can be signaled due to a race condition.
This also ensures the i2c device itself is in idle state before futzing
around with it.
Also, add a comment about the SI-flag in the I2C CTRL register; it has
a hidden dual meaning. Not only does it clear a pending interrupt, it
also moves the I2C IP state machine forward. This requires extra logic
in the driver to cope.
This selects ARM_THUMB for ARMV7R per ARM document:

Thanks to hujun260 for spotting this, now ostest works.
Why it helps is still to be clarified, the `arm_signal_handler.S`
might require this THUMB option.
To keep ARM_THUMB as option, this only selects it for
PROTECTED as per anchao's suggestion.
