spi: pl022: don't use uninitialized variable
The num-cs property is a required property according to the binding
documentation. However, if it is not present, the driver currently
simply uses random junk from the stack for the num-cs since the variable
whose pointer is passed to of_property_read_u32() is not initialized.
