[PATCH v5 40/52] docs: fpga: replace :c:member: macros

[Mauro Carvalho Chehab <mchehab+huawei@kernel.org>]

Those macros are not doing the right thing with Sphinx 3,
causing parse errors:

	./Documentation/driver-api/fpga/fpga-mgr.rst:104: WARNING: Unparseable C cross-reference: 'fpga_manager->state'
	Invalid C declaration: Expected end of definition. [error at 12]
	  fpga_manager->state

	./Documentation/driver-api/fpga/fpga-programming.rst:18: WARNING: Unparseable C cross-reference: 'fpga_region->info'
	Invalid C declaration: Expected end of definition. [error at 11]

	./Documentation/driver-api/fpga/fpga-region.rst:62: WARNING: Unparseable C cross-reference: 'fpga_region->get_bridges'
	Invalid C declaration: Expected end of definition. [error at 11]
	  fpga_region->get_bridges
	  -----------^

Replace them by :c:expr:, with does what's desired.
