Thomas Petazzoni 5c4fee63c5 gpio: pca953x: use a per instance irq_chip structure 
When a system has two PCA953x GPIO expanders, the kernel complains with:

gpio gpiochip2: (0-0021): detected irqchip that is shared with multiple gpiochips: please fix the driver.

Indeed, there is a single instance of "struct irq_chip" that gets
re-used for both PCA953x instance. This commit moves the "struct
irq_chip" to be part of the "struct pca953x_chip", so that we have one
"struct irq_chip" per PCA953X instance.

As part of this, the name of the irq_chip is also made different on a
per-instance basis, now using the dev_name() of the I2C device. This
changes what is visible in /proc/interrupts.

Before:

 47:          0          0   pca953x  10 Edge      e0100000.sdhci cd
 48:          0          0   pca953x   6 Edge      e0101000.sdhci cd

After:

 47:          0          0    0-0020  10 Edge      e0100000.sdhci cd
 48:          2          0    0-0020   6 Edge      e0101000.sdhci cd
