669331d0c4 pcnt: properly clear interrupt status in pcnt_intr_service
status is 0 when pcnt_hal_clear_intr_status() is called and so the
interrupt will be triggered immediatly again. Store the original
status and pass this as mask to pcnt_hal_clear_intr_status().

1966f00f0b soc: updates caps usage
We should define caps as 1 if true. When use the caps macros, #if and
 #if ! should be used instead of #ifdef/#ifndef.

647dea9395 soc: combine xxx_caps.h into one soc_caps.h
During HAL layer refactoring and new chip bringup, we have several
caps.h for each part, to reduce the conflicts to minimum. But this is
The capabilities headers will be relataive stable once completely
written (maybe after the featues are supported by drivers).

Now ESP32 and ESP32-S2 drivers are relative stable, making it a good
time to combine all these caps.h into one soc_caps.h

This cleanup also move HAL config and pin config into separated files,
to make the responsibilities of these headers more clear. This is
helpful for the stabilities of soc_caps.h because we want to make it
public some day.

4c57f50fe4 TWAI: ISR runs when cache is disabled
This commit adds the feature where the TWAI ISR will continue to
run even if the cache is disabled. Whilst cache is disabled, any
received messages will go into the RX queue, and any pending TX
messages in the TX queue will be transmitted. This feature should
be enabled using the CONFIG_TWAI_ISR_IN_IRAM option.

1393520e78 spi_slave: fix crash issue caused by setting cs to -1
Setting cs num to -1 means cs pin is not connected. But passing the value -1 to the
spicommon_cs_initialize() will lead to program crash caused by "array index out
of bounds". We expect the driver to execute well but the driver should not be in
charge of users' behaviour, so this commit prevents the crash.

27a6f2666a spi_master: refactor hal context structures
This commit seperates the hal context into different configuration
structures based on their members' definitions. Through refactoring
spi_master.c, the device related configuration should be passed in and
set each time before a new transaction. The transaction related
configuration now is a local variable in case of the fact that error
occurs without any notice when user forgets to pass new transaction
configuration in (which means the old driver will use the trans_config
that is saved from last transaction).

Besides, via above refactor, this commit fixs a bug which leads to
wrong cs polarity setting.
Closes https://github.com/espressif/esp-idf/pull/5490

Moreover, via above refactor, this commit also fixs a bug about duplex
mode switching when multiple devices are added to the bus.

46713a5275 driver(uart): fix uart module reset issue
On ESP32, due to fifo reset issue, UART2 will work incorrectly if reset the fifo of UART1(TX fifo and RX fifo). The software can workaround the RX fifo reset issue,

        while the TX fifo reset issue can not. When UART2 is used and UART1 is used as the log output port, a software reset can reproduce this issue. So we should reset the UART memory

        before the software reset to solve this problem.
