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.

3abdd2207d freemodbus: fix long buffer failure
check master read write functions with array of registers)
fix master serial processing code and modbus controller to work with register array
modbus_master: add reading and writing of test value array (58 registers) to check failure is gone
remove parameter temporary buffer from modbus controller to allow more than 24 byte writes
driver: fix issue with TOUT feature
driver: fix uart_rx_timeout issue
driver: fix issue with rxfifo_tout_int_raw not triggered when received fifo_len = 120 byte and all bytes read out of fifo as result of rxfifo_full_int_raw
driver: add function uart_internal_set_always_rx_timeout() to always handle tout interrupt
examples: call uart_internal_set_always_rx_timeout() to handle tout interrupt correctly
examples: update examples to use tout feature
driver: reflect changes of uart_set_always_rx_timeout() function, change uart.c
driver: change conditions to trigger workaround for tout feature in uart.c
driver: change uart_set_always_rx_timeout()
freemodbus: fix tabs, remove commented code
driver: remove uart_ll_is_rx_idle()

update set_rx_timeout() to warn user about incorrect value
update HAL, LL 1
fix uart_xx_set_rx_tout() to convert symbol time into bit time
update param description
update tout calculation in LL
update uart_hal_get_max_rx_timeout_thrd() and uart_ll_get_max_rx_timeout_thrd()
