[Impact] Disable these options for hardware that does not exist in the Google cloud fabric. There should be no impact to existing users. [Fix] CONFIG_DELL_SMBIOS_SMM=n CONFIG_DELL_UART_BACKLIGHT=n CONFIG_I2C_AMD_MP2=n [Test Plan] Boot a GCP instance and ensure there are no new kernel log errors. [Where problems could occur] Regression potential should be low since this HW does not exists in a GCP guest instance.
