Disable CONFIG_DELL_SMBIOS_SMM, CONFIG_DELL_UART_BACKLIGHT, CONFIG_I2C_AMD_MP2

[Tim Gardner]

SRU Justification:

Enforcement annotations indicate that these config options should never have been set.

[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.
