SPI2 failed as slave on MPC5748G devkit

[dongran]

1. Environment: S32DS, EAR0.8.1, MPC5748G DEVKIT
2. It seems there is something wrong with SPI2 while configuring it as slave,SPI_SlaveTransferBlocking can't return successfully due to it can't receive data even if master is sending data correctly.
3. In my case, I use the following ports and configure them as spi2 slave usage, then another DEVKIT as master, I can see the signal is fine on oscilloscope.

      SS                   PG11

      CLK                 PE15     

      SOUT              PG15

      SIN                  PG14

4. Please confirm if there is any problem with the EAR 0.8.1 or chip internal.
