ca8210: Fix crash by zero initializing data
The struct cas_control embeds multiple generic SPI structures and we
have to make sure these structures are initialized to default values.
This driver does not set all attributes. When using kmalloc before some
attributes were not initialized and contained random data which caused
random crashes at bootup.
