Changes for Aeon lite - notably 1MB ram support and ise build warnings fixed

Added 32-byte write support to ROM area! For MIST external sector buffer. TODO: Smarter method...

Added simple dma for faster sd card reading

Allow SPI clock speed to be set by generic. It was running at half speed for 28MHz platforms vs 58MHz platforms. Need to improve spi speed since byte wise writing is too slow loading roms - 8 seconds on startup!

Added missing spi component! Fix pokey instantiation. Fix pause.

Clock pause by pokey enable, so its a fixed speed even if system clock 28MHz,57MHz or otherwise

Renamed poly_* to pokey_poly_* since it is part of pokey

Cleaned up ZPU into slightly more generic form, though still clearly atari core targetted. Added inital tb, though needs rom to verify more. MIST sector side removed, but should be possible with external changes. Now ZPU instead has lots of GPIO.

Current unmerged vhdl for my Atari800 core and start at merging them into one tree with a common core
