- Add opensbi_version, this gives information of opensbi revision on
which the sbi_platform table was created.
- Add platform_version field in sbi_platform structure for platform
level version control.

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

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.

platform should be a read-only variable, if it is placed in the data
segment, it may be exploited.

As per the current SBI specification, sbi_getc should return
an int instead of char.
In case of FIFO is empty, return -1 as per the specification.

There was a space instead of '_' in the function `platform_final_init`.

Makes for easy and quick build-run one-stop command.
For now only added for qemu targets. It can be added for
any platform having simulator/emulator (such as QEMU).

This patch introduces following optional PLATFORM options:
PLATFORM_RISCV_XLEN -> RISC-V register width
PLATFORM_RISCV_ABI -> RISC-V GCC ABI
PLATFORM_RISCV_ISA -> RISC-V GCC ISA string
PLATFORM_RISCV_CODE_MODEL -> RISC-V GCC Code Model
If the above options are not provided by platform config.mk
or by command-line parameters then:
1. PLATFORM_RISCV_XLEN will be determined using toolchain
capability
2. PLATFORM_RISCV_ABI, PLATFORM_RISCV_ISA, and
PLATFORM_RISCV_CODE_MODEL is set to value best suited for
generic libsbi.a
As a result of these optional PLATFORM options, the
platform-cflags-y and platform-asflags-y is further
simplified for platform config.mk.

Both FW_JUMP_ADDR and FW_PAYLOAD_OFFSET, should be:
1. 4MB aligned for 32bit system
2. 2MB aligned for 64bit system
Explicitly specify the above details in config.mk comments
for template platform.

In order to support 32-bit guests move the start address to a 4MB
allignment. As 64-bit kernels have a requirement on being 2MB alligned
let's just make this the default for both 32 and 64 bit kernels.

The QEMU virt machine can be either 32 or 66 bit. Don't hard code the
CPU bit length and instead let the compiler determine it.
