    ASoC: rsnd: Fix RSND_SOC_MASK width to single nibble

    RSND_SOC_MASK was defined as (0xFF << 4), spanning bits 4-11. This is
    wider than needed since only nibble B (bits 7:4) is used for SoC
    identifiers. Narrow it to (0xF << 4) to match the intended single-nibble
    allocation and prevent overlap with bits 8-11 which will be used by
    upcoming RZ series flags.

    No functional change, since the only current user (RSND_SOC_E) fits
    within a single nibble.
