ASoC: fsl_rpmsg: update Kconfig dependencies

SND_SOC_IMX_RPMSG gained a new dependency and gets selected by SND_SOC_FSL_RPMSG,
which as a result needs to have the same dependency, or produce a build failure
based on that:

WARNING: unmet direct dependencies detected for SND_SOC_IMX_RPMSG
  Depends on [n]: SOUND [=y] && SND [=y] && SND_SOC [=y] && SND_IMX_SOC [=y] && RPMSG [=y] && OF [=y] && I2C [=n]
  Selected by [y]:
  - SND_SOC_FSL_RPMSG [=y] && SOUND [=y] && SND [=y] && SND_SOC [=y] && COMMON_CLK [=y] && RPMSG [=y] && (SND_IMX_SOC [=y] || SND_IMX_SOC [=y]=n) && SND_IMX_SOC [=y]!=n
