software/liblitedram/sdram: remove SRAM hack.
...
We now have memtest bios functions to test memories and testing SRAM while used by the BIOS is probably not a good idea.

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.

Storage in SPI Flash is generally limited and booting Linux from it is no longer very useful
