Adding chips TCA9554 and PCA9552, to expose the presence

Hi,
I have added chips TCA9554 and PCA9552  which will be used for presence
detect of FRUs, and line-names for miscellaneous GPIOs  .

Subject: [PATCH] Adding chips TCA9554 and PCA9552, to expose the presence
 detect lines for the op-panel, TPM, DASD planers, cable-cards, DCMs, VRMs.
 And line-names for miscellaneous GPIOs.
