mb/google/brya/var/gimble: Swap TPM I2C with touchscreen I2C
DVT schematic will exchange TPM_I2C3 to TPM_I2C1, that may need swap TPM I2C with touchscreen I2C to avoid TPM I2C fall on muxed ISH I2C, need change I2C map, sch amd GPIO map. b/196293623 BUG=b:207613972 TEST=USE="project_gimble emerge-brya coreboot" and verify it builds without error.
