Remove wifi config option
Remove Wi-Fi enable/disable option from Kconfig. This can be detected by the presence of esp_wifi_init() function in the application. Minimum footprint impact after the change.

SD SPI mode driver
This MR adds functionality to support SD cards connected via SPI interface.
Additionally, two bugs are fixed:
- Definition of `SPI_TRANS_MODE_DIOQIO_ADDR` in spi_master driver
- SD card probing frequency was 4000kHz instead of 400kHz as required by the standard

NVS is used to store PHY calibration data, WiFi configuration, and BT
configuration. Previously BT examples did not call nvs_flash_init,
relying on the fact that it is called during PHY init. However PHY init
did not handle possible NVS initialization errors.
This change moves PHY init procedure into the application, and adds
diagnostic messages to BT config management routines if NVS is not
initialized.

Implements support for system level traces compatible with SEGGER
SystemView tool on top of ESP32 application tracing module.
That kind of traces can help to analyse program's behaviour.
SystemView can show timeline of tasks/ISRs execution, context switches,
statistics related to the CPUs' load distribution etc.
Also this commit adds useful feature to ESP32 application tracing module:
- Trace data buffering is implemented to handle temporary peaks of events load
- Fix slave initiate service discovery procedure
- Fix master re-discovery every time connection established
- Optimize service discovery char ccc write procedure
- Optimize esp_log_buffer function
- Modify default supervision timeout from 20s to 2s
To increase the chances that the examples work out of the box, this
change is raising the default deep sleep wakeup delay to 1ms.
If GPIO15 is low at startup, ROM code takes less time to execute
(because no logging is performed), so more time may be needed to allow
flash chip to become ready.
1. Name change from chopper to carrier, block diagram update, minor changes to example codes
2. mcpwm_reg.h changed, brought uniformity in comments, worked on suggestions, duty to accept float. Some name changes!
3. Minor readme changes and Indetation
4. Minor change: move mcpwm_reg.h and mcpwm_struct.h to new path
5. Minor change: addition of BLDC example code and Readme
6. Name changed from epwm to mcpwm
7. Improve the reg name in mcpwm_struct.h
8. Name change chopper>carrier, deadband>deadtime
add API to get chip info
This change adds an API to get chip info, such as chip model, enabled capabilities, size of embedded flash, silicon revision.
Hello_world example is modified to print out the information about the chip. The example is also simplified by moving all code into the main task.
