ARM: shmobile: defconfig: Replace DRM_RCAR_HDMI by generic bridge options

The manual bridge implementation was removed in favor of the generic
one, so now we need to enable standard bridge drivers like
DRM_DUMB_VGA_DAC and DRM_I2C_ADV7511.
DRM_I2C_ADV7511 was already enabled, but the (newer) audio part wasn't.
