[PATCH 3/3] ASoC: meson: axg-spdifin: remove comparison always false warning

Fix W=1 warning:

sound/soc/meson/axg-spdifin.c: In function ‘axg_spdifin_write_mode_param’:
include/linux/bits.h:26:28: warning: comparison of unsigned expression
< 0 is always false [-Wtype-limits]

Cast width to an int to avoid checking if an unsigned value is lower
than zero.
