Subject: [PATCH 2/3] drm: bridge: adv7511: remove s32 format from i2s capabilities

The ADV7511 chip allows 24 bits samples max in I2S mode, excepted for
direct AES3 mode (SNDRV_PCM_FORMAT_IEC958_SUBFRAME_LE format).
However the HDMI codec exposes S32_LE format as supported.
Adapt ADV7511 HDMI I2S format list to expose formats actually supported.
