Update serial drivers to use DT_HAS_<compat>_ENABLED Kconfig symbol
to expose the driver and enable it by default based on devicetree.
We remove 'depend on' Kconfig for symbols that would be implied by
the devicetree node existing.

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.

This patch add support for polling based UART
on the Renesas R-Car SCIF (Serial Communication Interface
with FIFO)
This hardware block can be found on various Renesas R-Car
SoC series.
It allows to get console on R-Car Gen3 H3ULCB board.
