Two commits to solve exceptions

1. The SPI driver change fixed buffer overwrite bug in Freescale SPI driver.
2. The exception in qman_high.c can be resolved by upgrading Freescale kernel from SDK1.4 to SDK 1.5.
     The base kernel versions are the same 3.8.13.   This is done by applying a diff from tag fsl-sdk-1.4 to fsl-sdk-1.5
