Anson Huang dffe969aa7 Input: imx_sc_key - correct SCU message structure to avoid stack corruption ...

The SCU message's data field used for receiving response data from SCU
should be 32-bit width, as SCU will send back 32-bit width data.

This solves kernel panic when CONFIG_CC_HAVE_STACKPROTECTOR_SYSREG is
enabled.
