Add AS4C32M8SA-7TCN 32MB SDRAM used on cartridge PCB
by Jacob Creedon for the Hackaday Supercon ECP5 badge.
These changes were orginally made by Michael Welling:
https://github.com/mwelling/litedram
KiCad design files for the SDRAM cartridge:
https://github.com/jcreedon/dram-cart/
The SDRAM cartridge PCB is shared at:
https://oshpark.com/shared_projects/IQSl2lid
shared DigiKey cart of the parts:
https://www.digikey.com/short/p1ct1h

init: improve legibility of generated/sdram_phy.h (cosmetic)
...
Use DFII_NPHASES constant (defined earlier in the file) to size the
two 'sdram_dfii_pix_[wrdata|rddata]_addr' arrays, instead of a bare
number. Additionally, ensure the first array element is indented by
a tab, same as the ones following it.
