[PATCH v4 1/5] fpga: zynq: Fix incorrect variable type

[Nava kishore Manne <nava.manne@xilinx.com>]

zynq_fpga_has_sync () API is expecting "u8 *" but the
formal parameter that was passed is of type "const char *".
fixes this issue by changing the buf type to "const char *"

This patch will also update zynq_fpga_has_sync () API description
to align with API functionality.
