We should expand the FDT size before any patching, otherwise it's
possible the "status" fix up might fail due to insufficient space.

Per device tree spec, the standard value string for the "status"
property of a cpu node is either "okay" or "disabled". "masked"
was once used but it is unfortunately a spec violation.

Move platform opensbi functions to sbi_platform_operations structure.
Both sbi_platform and sbi_platform_operations structures are maintained
by platform vendors.

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.

One of the shortcomings of clang-format is that it doesn't allow
for aligned define tables, which is used for a number of constants.
Add annotation to disable the automatic formatting where needed.

Currently, only hart 1 is enabled for fu540 platform to support U-boot.
Introduce a compile time FU540_ENABLED_HART_MASK option so that specific
harts can be selected for booting. As fu540 is a multicore, we should
boot all cores by default except hart 0.

We rename sifive/hifive_u540 platform support to sifive/fu540
to match the SoC name which is SiFive FU540 (as-per user manual).
In fact, we can expect no (or very minimal) board specific
quirks in sifive/fu540 platform support. These board specific
quirks can be turned on/off in-future using PLATFORM_<xyz>
make command-line option.
