The error check 'plic_off < 0' does nothing, since plic_off is stored as
a u32. Fix this by changing it to an int, which matches the return type of
fdt_node_offset_by_compatible().

Although it does not make a functional difference, both cpu_to_fdt32()
and fdt32_to_cpu() pass on to CPU_TO_FDT32, we should use cpu_to_fdt32()
to be semantically correct.

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.

The drivers and libfdt are built as libsbiutils.a
instead of libplatsbi.a.
libsbiutils.a are not built per platform specific. Thus,
enable all drivers by default.

All string functions are part of libsbi. It makes more sense
to rename them to sbi_string.x as the libsbi can be linked
with external libraries that can have similar implementation.

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.
