Until now the pca953x driver accessed all the bank of a given register in a single command using only a 32 bits variable. New expanders from the pca53x family come with 40 GPIOs which no more fit in a 32 variable. This patch make access to the registers more generic by relying on an array of u8 variables. This fits exactly the way the registers are represented in the hardware. It also adds helpers to access to a single register of a bank instead of reading or writing all the banks for a given register.
