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
