[U-Boot] [PATCH v2 2/3] arm: spear: enable SSP1, 2 and 3 clocks when SPI controller driver is built

[Quentin Schulz]

SPI controllers SSP1, 2 and 3 require to enable their respective clocks.
Let's enable them only when the SPI controller driver is built.

  - define and use constants for enabling SSP1/2/3 clocks when the
  controller is built
