drm/bridge: ti-sn65dsi86: Fix multiple instances
Each bridge instance creates up to four auxiliary devices with different
names. However, their IDs are always zero, causing duplicate filename
errors when a system has multiple bridges:
sysfs: cannot create duplicate filename '/bus/auxiliary/devices/ti_sn65dsi86.gpio.0'
Fix this by using a unique instance ID per bridge instance. The
instance ID is derived from the I2C adapter number and the bridge's I2C
address, to support multiple instances on the same bus.
