The clint_ipi_sync() was removed long time back hence we remove
redundant declaration from clint.h

We add fdt_parse_uart8250_node() function which will allow us
to parse a particular DT node as UART 8250 node. This will be
useful in parsing the node pointed by stdout-path.

The information parsed by fdt_parse_uart8250() API is not complete.
We need to parse reg-shift and reg-io-width for UART 8520 as well.

This patch factor-out SiFive test device related stuff into
it's own source file from qemu/virt platform. In future, we
can find SiFive test device address from device tree as well.

We can achieve shutdown, cold reboot, and warm reboot using just
one sbi_platform callback so we combine system_reboot() and
system_shutdown() callbacks into one system_reset() callback.

FDT helper file contain both fdt fixup and parsing functions.
Split the fixup related functions to a separate file for a better code
organization.

Different DT based platforms from the sam family may reuse IP blocks with
different configurations. These different configurations can be obtained
by parsing the device tree.
Add a FDT parser framework that can parse various device configurations from
device tree. Currently, the parsing algorithms doesn't cover all the use cases
or possible combination of DT configurations. It will be improved over time.

Add a helper routine to updates the "status" property of a CPU node
in the device tree to "disabled" if that hart is in disabled state.

Now that we have a dedicated fdt_helper.c file for DT releated
helper routines, move plic_fdt_fixup() codes from plic.c to
fdt_helper.c and rename it to fdt_plic_fixup() at the same time,
to keep name consistency in the same file.

It is possible to have a CLINT implementation which supports
only 32bit MMIO accesses on RV64 system so this patch extends
our CLINT driver such that platform code can specify whether
CLINT supports 64bit MMIO access.

tinyfdt.c was originally added to provide a minimal implementation of
fdt parsing. However, we have already included libfdt in OpenSBI for
more complicated operations.
Remove tinfdt and replace its functiolity using libfdt.

Currently, platform/common contains platform/non-platform specific
common minimal drivers and libraries. This is helpful is all platforms
are built within opensbi framework.
Move them to lib/utils so that any external platform code also can
reuse the minimalistic drivers or other common libraries.
This patch doesn't introduce any functional changes.
