ASoC: codecs: rt1320-sdw: Refactor to reduce stack frames

Compiler is not happy about used stack frames in a couple of functions:

sound/soc/codecs/rt1320-sdw.c: In function 'rt1320_rae_load':
sound/soc/codecs/rt1320-sdw.c:1570:1: error: the frame size of 1336 bytes is larger than 1280 bytes [-Werror=frame-larger-than=]
sound/soc/codecs/rt1320-sdw.c: In function 'rt1320_dspfw_load_code':
sound/soc/codecs/rt1320-sdw.c:1786:1: error: the frame size of 1520 bytes is larger than 1280 bytes [-Werror=frame-larger-than=]

Refactor the code to fix these.
