b90a279587 feat(lp-core): Added ability to print from LP ROM on the LP core 
This commit adds the ability to use LP ROM functions from the LP core.
This allows the LP core code to utilize standard functions such as those
for printing from the LP ROM and therefore help reduce the code size on
the LP core.

287bdc5e61 fix(test_apps): Trim builds of component test apps 
Some component test apps do not use the "set(COMPONENTS main)" command in their
project level "CMakeLists.txt", thus leading to their builds pulling in all
ESP-IDF components.

This commit trims the build of multiple component test apps:

- Add "set(COMPONENTS main ...)" to project level "CMakeLists.txt"
- Add missing "PRIV_REQUIRES" in some "main" component "CMakeLists.txt"

Also removed repeated configuraiton options in legacy_i2c_driver/sdkconfig.ci.defaults

This commit updates the LP_I2C driver used by the LP CPU wherein the
driver did not send out a NACK when we do a read of multiple of the FIFO
depth bytes. This was because the LP I2C controller was configured to
send an ACK when the Rx FIFO reaches the threshold instead of a NACK.
This commit updates the behavior.

662e0812f4 ulp-riscv-i2c: Add ULP RISC-V I2C read/write timeout config option 
The commit 88e4c06028 introduced a loop timeout for all ULP RISC-V I2C
transactions to avoid getting stuck in a forever loop. The loop timeout
was set to 500 msec by default. This commit improves on the concept by
making the loop timeout configurable via a Kconfig option in terms of
CPU ticks. If the timeout is set to -1 value then the transaction loops
will never timeout, therefore restoring the driver behavior before the
timeout was introduced.

The commit also updates the I2C Fast mode timings for esp32s2 which need
to be adjusted due to bus timing constraints.

88e4c06028 ulp-riscv-i2c: Updated ULP RISC-V I2C driver to abort when met with errors 
The current ULP RISC-V RTC I2C driver got stuck in an infinite loop if
there is a I2C transaction error. This commit amends the driver flow to
abort the read/write operation if met with errors. It also adds a loop
timeout to avoid getting stuck in an infinite loop.The commit also
updates the default bus timing parameters for RTC I2C to be faster.
This commit also adds documentation help to guide users when they meet
with issues while working with the RTC I2C driver on the ULP RISC-V coprocessor.

This commit updates the ULP CMakeLists.txt to output the ULP binary with
a .elf extension. Currently the output file does not use any extension.

3cc399f399 ulp-riscv: Added API ulp_riscv_reset to reset the ULP core 
This commit adds a new API ulp_reisv_reset() to enable reseting of the
ULP core from the main core. This is particularly necessary in case the
ULP crashes due to any reason. Earlier the only way to recover the ULP
was to do a power reset. This commit also adds new test cases which
exercise this scenario.

4a410391cc ulp risc-v rtc i2c: Fix a bug where RTC I2C failed to initialize after esp_restart() 
This commit fixes a bug wherein the RTC I2C peripheral got stuck after
the main CPU performs a soft reset by using esp_restart(). This is
because the RTC domain config registers for the RTC I2C domain are not
cleared after the soft restart and hence need to be cleared manually
while initializing the RTC I2C peripheral again.

07a506bb02 ulp-riscv-i2c: Updated API documentation about sub register address usage 
The RTC I2C peripheral always expects a I2C slave sub register address
to be programmed. If it is not programmed then a sub register address
available in SENS_SAR_I2C_CTRL_REG[18:11] is used for I2C read/write.
This commit updates the documentation of the API
ulp_riscv_i2c_master_set_slave_reg_addr() to clarify the same.
