647dbdbcaf Update i2c.c 
Fix issue with single bus clear counter but two I2C buses (I2C0, I2C1). The previously implemented single (static) counter would impact the second bus either if one bus has counter expiry.

cb411a81a2 I2C: Fix a bug making the I2C task wait too long on an event 
The I2C ISR will now notify the task waiting on an event. Thus, the task can stop waiting on the event queue as soon as possible.

2575c0d49f i2c: fix I2C slave clock source selection 
In I2C slave mode, clock source can now be changed, according to
the flags specified in `i2c_config_t` structure. Thus, ESP32-S2
can now act as an I2C slave, even with a 400KHz master clock.

7dd499d1f4 i2c: commands can now be re-used without deleting and creating new cmd links 
It is now possible to call `i2c_master_cmd_begin()` on the same
`i2c_cmd_handle_t` parameter. Thus, no extra allocation will be performed.
Moreover, as commands contains pointers to data, these can be modified
between two calls to `i2c_master_cmd_begin()`. This becomes very handy
for framebuffers.

cd79f3907d gpio: Disable USB JTAG when setting pins 18 and 19 as GPIOs on ESP32C3 
When `DIS_USB_JTAG` eFuse is NOT burned (`False`), it is not possible
to set pins 18 and 19 as GPIOs. This commit solves this by manually
disabling USB JTAG when using pins 18 or 19.
The functions shall use `gpio_hal_iomux_func_sel` instead of
`PIN_FUNC_SELELECT`.

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.
