Adds status interface for zynqmp-fpga. It's a read only interface
which allows the user to get the Programmable Logic(PL) configuration
status.
Usage:
To read the Programmable Logic(PL) configuration status.

The FPGA manager class driver data structure is being treated as a
managed resource instead of using the standard dev_release call-back
function to release the class data structure. This change removes
the managed resource code for the freeing of the class data structure
and combines the create() and register() functions into a single
register() or register_full() function.
The register_full() function accepts an info data structure to provide
flexibility in passing optional parameters. The register() function
supports the current parameter list for users that don't require the
use of optional parameters.
The devm_fpga_mgr_register() function is retained, and the
devm_fpga_mgr_register_full() function is added.

An FPGA manager should not be required to provide a
write_complete function if there is nothing. Move
the op check to the existing wrapper.
Default to success and remove noop function.

Use direct function call instead of using eemi ops for fpga related
APIs. Also remove eemi ops structure.

Fixes the following static checker errors:
drivers/fpga/zynqmp-fpga.c:50 zynqmp_fpga_ops_write()
error: 'eemi_ops' dereferencing possible ERR_PTR()
drivers/fpga/zynqmp-fpga.c:84 zynqmp_fpga_ops_state()

Note: This does not handle the EPROBE_DEFER value in a
special manner.
