Subject: [PATCH v2 2/2] ARM: dts: AM437x-gp-evm: Add wakeup interrupt source for pixcir_i2c_tsc

Pixcir_i2c_tsc driver can now wakeup the system from lower power state
via pinctrl and IO daisy chain using generic wakeirq framwework. Add
optional wakeup irq entry to allow pixcir_i2c_tsc to wake system from
low power state.
