Not all systems have bash at a fixed location like /bin/bash.
FreeBSD, for example, would typically have it at /usr/local/bin/bash.
When building OpenSBI on freebsd system, the build breaks.
Its advisable to use: #!/usr/bin/env bash

Currently, if same build directory is used to compile two different
platforms then lib/utils objects are shared for these platforms.
We will be having platform specific configs to enable/disable drivers
in lib/utils and select compile time options for lib/utils sources.
This means lib/utils sources will now be compiled in a platform
specific way.
To tackle above, we update top-level Makefile as follows:
1) Don't create libsbiutils.a anymore because this can't be shared
between platforms.
2) Compile lib/utils sources separately for each platform.
3) Add comments showing which make rules are for lib/sbi, lib/utils,
firmware, and platform sources.

Generating C array at compile time based on details provided by
objects.mk is a very useful feature which will help us compile
only a subset of drivers or modules.
We add a bash script (carray.sh) which takes array details and
object/variable list from command-line to generate a C source
containing array of object/variable pointers. We also extend
top-level makefile to use carray.sh whenever specified through
objects.mk.

Currently, we can only include one DTB as builtin for a platform
using FDT_PAYLOAD_DTB make variable in platform config.mk.
This patch adds new mechanism using which we can convert any DTS
file to C source and futher compile-n-link it with libplatsbi.a.
The generated C source will have the DTB contents as an array
"const char <varprefix>_start[]" where <varprefix> is specified
in platform objects.mk makefile.
Example1
--------
If we have built-in k210.dts and desired <varprefix> is
"dt_k210" then specify following in platform objects.mk:
platform-objs-y += k210.o
platform-varprefix-k210.o = dt_k210
Example2
--------
If we have built-in abc/k210.dts and desired <varprefix> is
"dt_abc_k210" then specify following in platform objects.mk:
platform-objs-y += abc/k210.o
platform-varprefix-abc-k210.o = dt_abc_k210
