bios/software: rename cmd_dram/cmd_sdcard/cmd_spi_flash to cmd_litedram/cmd_litesdcard/cmd_spiflash.

cpu/microwatt/add_sources: add use_ghdl_yosys_synth parameter to convert microwatt to verilog using GHDL-Yosys-plugin and use converted verilog for build.

Make booting from SD-Card to behave same as from SPI flash

soc/SoCController: add uptime since start (disabled by default) and allow features to be enabled/disabled.

csr: Rework accessors

Have all the new compound accessors be written in terms of the simple
ones and fix how CSR_ACCCESORS_DEFINED can be used to override the
simple ones but keep the definitions of the other ones around.

This *should* also also fix incorrect multiple accesses done
by  64-bit CPUs to 32-bit CSR busses, and make the accessors not
depend on CONFIG_CSR_ALIGNMENT being the same as sizeof(unsigned long)*8

In addition, the generated csr.h now will include system.h
always when with_access_functions is True. This guarantees that the
higher level accessors are defined. The extern prototypes for the
simple accessors when CSR_ACCCESORS_DEFINED are removed and system.h
is responsible for providing them. It is also added to hw/common.h

This allows system.h to set CSR_ACCCESORS_DEFINED when necessary, in
which case it's responsible for both declaring and defining the simple
accessors. That way, it can make them inline rather than forcing them
to be extern which at least on microwatt saves spaces.

One can continue to use -DCSR_ACCCESORS_DEFINED but in that case a system.h
will have to be provided with at least the extern definitions.

This will allow more flexibility when integrating standalone cores.

cpu/soc_core: automatically set csr mapping to 0x00000000 when using CPUNone, remove csr_base parameter that was used for that.

- copy_image_from_flash_to_ram is now used by all CPUs.
- copy_image_from_flash_to_ram already show the flash address, no need to duplicate it.
