add an option to generate without reg initializers (asic targets)
...
ASIC targets can't set a reg to a known value on boot, so for
more accurate simulations it would be nice to have an option
in the platform to specify generating the verilog without 'reg'
initializers. The presence of these initializers can mask
problems in simulations with X-prop that can lead to missing
explicit reset conditions.

bios/spiflash: bring back write and erase, add write from sdcard file cmd
...
When shipping MNT RKX7, I pre-flash the SPI flash with a LiteX bitfile
for testing. cmd_spiflash had regressed because of changed SPIFLASH defines
and didn't offer the write functions anymore. This commit fixes that, and
adds convenience functions:
- flash_erase_range <offset> <count (bytes)>
- flash_from_sdcard <filename>
The latter reuses some boot code to copy the contents of the specified
file from the boot FAT partition on the SD card to SPI flash (i.e.
a bitstream).
