dts: Allow specifying initrd position and size via args

This is needed as my initrd size is much larger than the default 8mb.
Also, sometimes the kernel I build is also large, so its good to be
able to move the initrd starting position.

software/bios: add new mem_list command to list available memory regions.

This is useful to know the memory regions available and use the mem_xy commands
on them:
List the memory regions:
litex> mem_list
Available memory regions:
ROM 0x00000000 0x8000
SRAM 0x01000000 0x2000
MAIN_RAM 0x40000000 0x10000000
CSR 0x82000000 0x10000
Test 0x1000 bytes of MAIN_RAM:
litex> mem_test 0x40000000 0x1000
Memtest at 0x40000000 (4KiB)...
Write: 0x40000000-0x40001000 4KiB
Read: 0x40000000-0x40001000 4KiB
Memtest OK
Test speed on 0x1000 bytes of MAIN_RAM:
litex> mem_speed 0x40000000 0x1000
Memspeed at 0x40000000 (4KiB)...

mor1kx: Enable rotate, sign extend under linux, new fpu extension
...
My thought is that if we are running linux the FPGA should be able to
handle these extra instruction's footprint. Also, since we are running
on linux there may be any kind of software running on the CPU, so allow
handling these instructions.
FPU is added bia a new +fpu extension.
But really, I am running GLIBC tests and they run faster with this
enabled.
