[PULL 38/83] hw/gpio: pca9552: declare pca9555 device as an alias of pca9535 device

From: Emmanuel Blot <[email protected]>

PCA9555 HW is mostly identical to PCA9535.
PCA9555 HW features pull-up resistors that are not available on PCA9535.

Pull-up are not handled by current PCA955x implementation and PCA9535
already initializes input as Hi-Z.
