Subject: [PATCH 4/5] ARM: Ux500: Change SPI mode and remove unused fields

From: Kevin Wells <wellsk40@...il.com>

Some of the fields in the pl022_chip_info structure used with
the amba pl022 driver are no longer used. This patch removes
those unused fields and changes the .mode flags in the
spi_board_info structure to setup the correct SPI mode.

Signed-off-by: Kevin Wells <wellsk40@...il.com>
