Fixed an issue where running debug online diagnostics run on a 5G supported PA-400 firewall models reported "Missing device on I2C bus" errors and did not execute cellular modem diagnostic tests. This occurred because the diagnostics script used an incorrect I2C device list for the 5G supported PA-400 hardware variants and did not recognize it as a cellular-capable platform. With this fix, the I2C scan correctly reflects the 5G supported PA-400 hardware configuration and cellular modem tests run as expected.
