ARM: zynq: Add support for the topic-miami system-on-modules and carrier boards
The topic-miami SoMs contain a Zynq xc7z015 or xc7z030 SoC, 1GB DDR3L RAM,
32MB QSPI NOR flash and 256MB NAND flash.
The topic-miamiplus SoMs contain a Zynq xc7z035, xc7z045 or xc7z100 SoC,
2x 1GB DDR3L RAM, 64MB dual-parallel QSPI flash, clock sources
and a fan controller.
The "Florida" carrier boards add SD, USB, ethernet and other interfaces.
