6b1292284e fix(lp_i2c): Fixed a bug where the LP_I2C did not send NACK for 16-byte reads
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.

a9ef76b031 fix(lp_i2c): Fixed a bug where LP I2C write got stuck
This commit fixes a bug where an I2C write got stuck when using the
lp_core_i2c_master_write_read_device() API. This was because the LP I2C
HW was not programmed with an END condition and therefore did not know
the end of a transaction.

Closes: https://github.com/espressif/esp-idf/issues/11958

ee8adce5ea fix(lp_i2c): Fixed incorrect clock setting for LP_I2C
The LP_I2C clock setting was incorrect and a lower frequency value was
being set during initialization. This commit fixes the behavior.
