In include/dfu.h, if CONFIG_SYS_DFU_MAX_FILE_SIZE is not defined then it is defined as CONFIG_SYS_DFU_DATA_BUF_SIZE. This is 128 KiB for a53 core and 20 KiB for r5 core. If a larger file is transferred using dfu then it fails.

CONFIG_SYS_DFU_DATA_BUF_SIZE can not be increased as there is not enough heap memory to be allocated for the buffer in case of R5 spl.

Fix this by defining CONFIG_SYS_DFU_MAX_FILE_SIZE as the default CONFIG_SYS_DFU_DATA_BUF_SIZE value.
