The single pinmux controller can be cascaded to the other interrupt
controllers. Hence when propagating wake-up settings to its parent
interrupt controller, there's possiblity of detecting possible recursive
locking and getting lockdep warning.
This patch avoids this false positive by using a separate lockdep class
for this single pinctrl interrupts.

I need Tony's ACK on this patch before applying.
Is it a regression that needs to go into fixes?
Not really, only needed by PATCH 2/2 to avoid recursive locking.
