ASoC: SOF: Intel: byt: Refactor fw ready / mem windows creation
There is a lot of duplicate code when processing IPC firmware ready notification and creating memory windows. First step in reducing the code duplication is to introduce generic functions: * sof_get_windows * sof_fw_ready that will replace, in the first step, the specific implementation related to baytrail related platforms: * byt_get_windows * byt_fw_ready So we are basically moving code from intel/byt.c to loader.c keeping in mind that mbox_offset is a per platform constant so we need to use newly introduced snd_sof_dsp_get_mailbox_offset / snd_sof_dsp_get_window_offset in order to get the correct mbox offset / window offset value. Also, bar is a per platform constant so we use snd_sof_dsp_get_bar_index instead of the hardcoded BYT_DSP_BAR.
