Charles Perry	4a1f12b5b5	fpga: xilinx-core: add new gpio names for prog and init ... Old names (prog_b and init-b) are used as a fallback for hardware compatible with the "xlnx,fpga-slave-serial" string.

Charles Perry	a52e3a9dba	fpga: xilinx-spi: extract a common driver core ... Factor out the gpio handshaking (using PROGRAM_B, INIT_B and DONE) protocol in xilinx-core so that it can be reused for another driver. This commit does not change anything functionally to xilinx-spi. xilinx-core expects drivers to provide a write(const char* buf, size_t count) function that performs the actual write to the device, as well as a struct device* for resource management.
