[PATCH 01/11] spi-dw: expose platform data stucture.

[dirk . brandewie]

From: Dirk Brandewie <dirk.brandewie@xxxxxxxxx>

Expose the platform data structure for use by client drivers. ATM
there are not any in-tree drivers using the driver (that I can
find). This patch exposes the platform data needed for client drivers.
