[PATCH v2] ARM: dts: am437x-gp-evm: Add wakeup interrupt source for pixcir_i2c_ts

[Vignesh R]

On am437x-gp-evm, pixcir_i2c_ts can wakeup the system from low 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.

Since v1:
 - correct interrupt flag.
 - add comment wrt wakeup interrupt.
