Convert how we get the various chosen properties like "zephyr,console"
to use the new kconfig functions like dt_chosen_to_label.
Because of how kconfig parses things we define a set of variables of the
form DT_CHOSEN_Z_<PROP> since comma's are parsed as field seperators in
macros.
This conversion allows us to remove code in gen_defines.py for the
following chosen properties:
zephyr,console
zephyr,shell-uart
zephyr,bt-uart
zephyr,uart-pipe
zephyr,bt-mon-uart
zephyr,uart-mcumgr
zephyr,bt-c2h-uart

Utilize the multi-level irq infrastructure and replace custom handling
for PLIC on riscv-privilege SoCs. The old code offset IRQs in drivers
and various places with RISCV_MAX_GENERIC_IRQ. Instead utilize Zephyr's
encoded IRQ and replace offsets in drivers with the IRQ define from DTS.

There are two aspects to this: CPU registers are twice as big, and the
load and store instructions must use the 'd' suffix instead of the 'w'
one. To abstract register differences, we simply use a ulong_t instead
of u32_t given that RISC-V is either ILP32 or LP64. And the relevant
lw/sw instructions are replaced by LR/SR (load/store register) that get
defined as either lw/sw or ld/sd. Finally a few constants to deal with
register offsets are also provided.

With the upcoming riscv64 support, it is best to use "riscv" as the
subdirectory name and common symbols as riscv32 and riscv64 support
code is almost identical. Then later decide whether 32-bit or 64-bit
compilation is wanted.
Redirects for the web documentation are also included.
Then zephyrbot complained about this:
"
New files added that are not covered in CODEOWNERS:
dts/riscv/microsemi-miv.dtsi
dts/riscv/riscv32-fe310.dtsi
Please add one or more entries in the CODEOWNERS file to cover
those files
"
So I assigned them to those who created them. Feel free to readjust
as necessary.
