drm/bridge: it66121: Initialize {device,vendor}_ids
These two arrays are populated with data read from the I2C device through regmap_read(), and the data is then compared with hardcoded vendor/product ID values of supported chips. However, the return value of regmap_read() was never checked. This is fine, as long as the two arrays are zero-initialized, so that we don't compare the vendor/product IDs against whatever garbage is left on the stack. Address this issue by zero-initializing these two arrays.
