Removing it completely would require revisiting the gateware/firmware code of the
UART. Since this is use for test purpose only and already allow > 600KB/s upload
speed, keeping it is acceptable.

software: use a single crt0 (deprecate crt0-ctr/crt0-xip) and avoid unnecessary defines.
...
Since https://github.com/enjoy-digital/litex/issues/566 , crt0-ctr and crt0-xip are now similiar
so we can get back to a single crt0 and remove the defines that were generated to distinguish
the different cases.
Since LiteX/MiSoC have diverged and are no longer compatible, we also no longer need to generate
the LiteX flag.

use more complex constructs and adds the TOC to the linker script

bios/boot: simplify flashboot (remove specific linux boot).
...
Storage in SPI Flash is generally limited and booting Linux from it is no longer very useful
since boot from SDCard is now supported. This is in the continuity of the SDCard/Ethernet
simplications to have an easier and more flexible boot scheme.

bios/boot: make SDCard boot more flexible using a boot.json file on the SDCard.
...
The BIOS now reads the boot.json file to know which files need to be copied to RAM and where.
It will fallback to boot.bin is no boot.json is found and boot will fail if neither is found.
Example of boot.json file used to boot Linux-On-LiteX-Vexriscv:
{
"Image": "0x40000000",
"rootfs.cpio": "0x40800000",
"rv32.dtb": "0x41000000",
"emulator.bin": "0x41100000"
