cpu/software: move CPU specific software from the BIOS to the CPU directories.

This simplifies the integration of the CPUs' software, avoid complex switches in the code,
and is a first step to make CPUs fully pluggable.
The CPU name is no longer present in the crt0 files (for example crt0-vexriscv-ctr.o
becomes crt0-ctr.o) so users building firmwares externally will have to update their
Makefiles to remove the $(CPU) from crt0-$(CPU)-ctr.o.

soc/cores/uart: use reset_less on accumulator, reg, bitcount to reduce.
...
This reduces logic a bit. It does not make large difference on usual design with
only 1 UART, but is interesting on designs with hundreds of UARTs used to "document"
FPGA boards :) (similar to https://github.com/enjoy-digital/camlink_4k/blob/master/ios_stream.py )

In `spi_sdcard_goidle()`, insert a `busy_wait()` into the CMD55+ACMD41

to be ready (required on the trellisboard, also tested OK on nexys4ddr).

soc: allow creating SoC without BIOS.
...
By default the behaviour is unchanged and the SoC will provide a ROM:
./arty.py
Bus Regions: (4)
rom : Origin: 0x00000000, Size: 0x00008000, Mode: R, Cached: True Linker: False
sram : Origin: 0x01000000, Size: 0x00001000, Mode: RW, Cached: True Linker: False
main_ram : Origin: 0x40000000, Size: 0x10000000, Mode: RW, Cached: True Linker: False
csr : Origin: 0x82000000, Size: 0x00010000, Mode: RW, Cached: False Linker: False
The integrated rom can be disabled with:
./arty.py --integrated-rom-size=0
but the SoC builder will check for a user provided rom, and if not provided will complains:
ERROR:SoC:CPU needs rom Region to be defined as Bus or Linker Region.
When a rom is provided, the CPU will use the rom base address as cpu_reset_address.
If the user just wants the CPU to start at a specified address without providing a rom,
the cpu_reset_address parameter can be used:
./arty.py --integrated-rom-size=0 --cpu-reset-address=0x01000000
If the provided reset address is not located in any defined Region, an error will
be produced:
ERROR:SoC:CPU needs reset address 0x00000000 to be in a defined Region.
When no rom is provided, the builder will not build the BIOS.

Add SVD export capability to Builder (csr_svd parameter) and targets (--csr-svd argument) and fix svd regression.
...
This allows generating SVD export files during the build as we are already doing for .csv or .json.
Use with Builder:
builder = Builder(soc, csr_svd="csr.svd")
Use with target:
./arty.py --csr-svd=csr.svd

build: assume vendor tools are in the PATH and remove automatic sourcing, source and toolchain_path parameters.
...
Automatic sourcing was not consistent between build backends (and only really supported by ISE/Vivado)
and had no real additional value vs the complexity needed to support it. Now just assume required vendor
tools are in the PATH.
This also removes distutils dependency.
