On am437x-gp-evm, pixcir_i2c_ts can wakeup the system from lower power
state via pinctrl and IO daisy chain using generic wakeirq framework.
With commit 3fffd1283927 ("i2c: allow specifying separate wakeup
interrupt in device tree") i2c core allows optional wakeirq to be
specified via device tree. Add wakeup irq entry to enable pixcir_i2c_ts
to wake the system from low power state.
