GPIO: PCA953X: Increase size of invert variable to support 24 bit
TCA6424 is a low voltage 24 bit I2C and SMBus I/O expander of pca953x family similar to its 16 bit predecessor TCA6416. It comes with three 8-bit active Input, Output, Polarity Inversion and Configuration registers each. The polarity of Input ports can be reversed by setting the appropiate bit in Polarity Inversion registers. The variables corresponding to Input, Output and Configuration registers have already been updated to support 24 bit values. This patch thus updates the invert variable of PCA953X platform data to support 24 bit.
