This commit add the support of "Interrupt driven UART"
to the R-Car UART driver and enable it in the related
Kconfig.
The driver is supporting nearly all the methods that are
described in the "Interrupt driven UART" part of the
uart_driver_api.
This new version of the driver has been tested on
H3ULCB board by running "uart_basic_api" test suite.
