MLK-10923 arm: pci: use the i2c expansion perst on imx6qp
Base on the following commit, use the i2c expansion
gpio as the pcie perst on imx6qp ard board.
"ab13b0e11c50021905de00a0f3c0df7e0a36a3f0"
i2c: imx: add irqf_no_suspend
The i2c irq is masked when pcie starts a i2c transfer process
during noirq suspend stage. As a result, i2c transfer fails.
To solve the problem, IRQF_NO_SUSPEND is added to i2c bus.
