parentwil6210: fix memory leak on error path in wil_write_file_rxon() (diff)

wil6210: use same mapping table for FW addr translation and debugfs
Use single data source for all information regarding the firmware memory map. With this change "ucode_xxx" regions disappears since they are in fact part of larger "upper area" region Signed-off-by: Vladimir Kondratiev <qca_vkondrat@qca.qualcomm.com> Signed-off-by: John W.
