add 32MB SDRAM for hadbadge
...
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:

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:

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.

The CSR alignment and base can be specified (which mostly affects
the generation of csr.h) andwe stop trying to copy the init code
that we haven't generated
