[PATCH v3 04/16] fpga: mgr: separate getting/locking FPGA manager

This commit makes it straightforward to save a reference to an FPGA manager and only lock it when programming the FPGA. Add functions that get an FPGA manager's mutex for exclusive use: * fpga_mgr_lock * fpga_mgr_unlock The following functions no longer lock an FPGA manager's mutex: *

[PATCH v3 02/16] fpga: bridge: support getting bridge from device

Add two functions for getting the FPGA bridge from the device rather than device tree node. This is to enable writing code that will support using FPGA bridges without device tree. Rename one old function to make it clear that it is device tree-ish. This leaves us with 3 functions for getting a
