remoteproc: Support custom firmware handlers
Firmware handling is made customizable. This is done by creating a separate ops structure for the firmware functions that depends on a particular firmware format (such as ELF). The ELF functions are default used unless the HW driver explicitly injects another firmware handler by updating rproc->fw_ops. The function rproc_da_to_va() is exported, as custom firmware handlers may need to use this function.
