spi: 9x25: Update platform data for mdm9625

Platform-data has the following misconfiguration:
1.Clock frequency: Device-Tree entries specify frequencies that
  are not present in the clock frequency table.
2.Bus-number: Missing bus-number specification in the Device-Tree
3.Clock lookup table: Pre-Device-Tree SPI device name in the
  clock lookup table.
4.Redundant aux-data entry:  Pre-Device-Tree aux-data entry in
  the board-file.
5.GPIOs: GPIOs are set to wrong number and function.
6.QUP: Wrong QUP numberand corresponding address and interrupt.

This patch updates and fixes the above items. It sets the clock
rate to the nearest lower frequency that is present in the clock
frequency table.
