esp32: Add reset uart

Browse source 
Fixed the case when the first part of log was missed
this was happened when:
 * CONFIG_CONSOLE_UART_CUSTOM option is selected (UART1)
 * The selected CONSOLE_UART port is used also for the console component
 * in code esp_restart() or abort() functions were called.
