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.

According to Kconfig guidelines, boolean prompts must not start with
"Enable...". The following command has been used to automate the changes
in this patch:
sed -i "s/bool \"[Ee]nables\? \(\w\)/bool \"\U\1/g" **/Kconfig*

The UART1 is not actually accessible on the HiFive1 since the
QFN48 package for the FE310, used by this board, does not expose the
required pads. However, it is still possible to use the UART1 on HiFive1
emulators (e.g. using UART0 for debugging and UART1 for SLIP).
Unfortunately, the UART0 and UART1 currently have different default
configurations when it comes to the configured transmission watermark
(txcnt). With a txcnt of zero (the default for UART1) the UART is not
actually usable (see #18118). Contrary to UART0 (see #23699), the UART1
does therefore not work by default on Zephyr which took me some time to
figure out.
This commit aligns the default UART1 configuration with the UART0,
thereby making it work by default.

This patch replace CONFIG_UART_SIFIVE_PORT_0_IRQ_PRIORITY into
interrupt-cell of device-tree to set IRQ priority.

A txcnt of zero prevents transmission, as transmit requires the number
of entries in the transmit fifo to be strictly less than the txcnt
value. Set the default to 1.

Use this short header style in all Kconfig files:
# <description>
# <copyright>
# <license>
...
Also change all <description>s from
# Kconfig[.extension] - Foo-related options
to just
# Foo-related options
It's clear enough that it's about Kconfig.
The <description> cleanup was done with this command, along with some
manual cleanup (big letter at the start, etc.)

FE310 is the name of one SoC out of a range of products in the SiFive
Freedom line. The FE310 SoC port in Zephyr is compatible with all of
these products, so rename the SoC to SiFive Freedom
