The 'boot_splash_filedata_size' was introduced as a global variable
in 3d3b8303. This variable is used as a 'size' argument to the
fw_cfg_add_file(). This function has an interface contract with its
'data' argument, but there is no such contract for 'size' (this is
not a referenced pointer).  We can simply remove it.
