bb70a2325a 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.

00f973ea35 spi_flash: extend non-bitbanged flash support 
This commit adds support for memory mapped writes
in the same configuration as memory mapped reads
are currently supported.

It also adds support for accessing registers
and erasing sectors in non-bitbanged single SPI
mode.
