Merge "Sunplus SP7021 SoC support" from Qin Jian, applied
as patches:

 "Sunplus SP7021 is an ARM Cortex A7 (4 cores) based SoC. It integrates many
  peripherals (ex: UART, I2C, SPI, SDIO, eMMC, USB, SD card and etc.) into a
  single chip. It is designed for industrial control.

  SP7021 consists of two chips (dies) in a package. One is called C-chip
  (computing chip). It is a 4-core ARM Cortex A7 CPU. It adopts high-level
  process (22 nm) for high performance computing. The other is called P-
  chip (peripheral chip). It has many peripherals and an ARM A926 added
  especially for real-time control. P-chip is made for customers. It adopts
  low-level process (ex: 0.11 um) to reduce cost.

I left out the clock controller driver, which is still not fully
reviewed. There have been 20 revisions of the platform code, and
everything else looks good enough, so I hope it's we can simplify
the process by separating it out again.
