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.
