firmware: xilinx: Export zynqmp_pm_fpga_{get_status,load}

When building arm64 allmodconfig:

ERROR: modpost: "zynqmp_pm_fpga_load" [drivers/fpga/zynqmp-fpga.ko] undefined!
ERROR: modpost: "zynqmp_pm_fpga_get_status" [drivers/fpga/zynqmp-fpga.ko] undefined!

These functions were added to drivers/fpga/zynqmp-fpga.c but not
exported so the module build breaks. Export them so that they can be
used in modules properly.

Fixes: 4db8180ffe ("firmware: xilinx: Remove eemi ops for fpga related APIs")
