c6x: convert fdt pointers to opaque pointers
The architecture code does not need to access the internals of the FDT
blob, so make the pointer to it void *.

c6x: use boot_command_line instead of private c6x_command_line
Save some pointless copying of the kernel command line and just use
boot_command_line instead.
Also remove default_command_line as it is not referenced anywhere, and
the DT code already handles the default command line.

C6X: add basic support for TMS320C6678 SoC
This patch adds support for the TMS320C6678 SoC on an EVMC6678LE
evaluation board. The 6678 is a C66x family CPU which is very similar
to the already supported C64x CPUs with the addition of floating point
instructions.

C6X: add register_cpu call
Commit ccbc60d3e19a1b6ae66ca0d89b3da02dde62088b requires CPU
topology information even in !SMP cases. This requires C6X to
add a call tp register_cpu() in order to avoid a panic at
boot time.

C6X: early boot code
Original port to early 2.6 kernel using TI COFF toolchain.
Brought up to date by Mark Salter <msalter@redhat.com>
This patch provides the early boot code for C6X architecture. There is a
16 entry vector table which is used to direct reset and interrupt events. The
vector table entries contain a small amount of code (maximum of 8 opcodes)
which simply branches to the actual event handling code.
The head.S code simply clears BSS, setups up a few control registers, and calls
machine_init followed by start_kernel. The machine_init code in setup.c does
the early flat tree parsing (memory, commandline, etc). At setup_arch time, the
code does the usual memory setup and minimally scans the devicetree for any
needed information.
