[PATCH 2/8] mfd: cros_ec_i2c: move the system sleep pm ops to late

[Thierry Escande <thierry.escande@collabora.com>]

From: Joseph Lo <josephl@nvidia.com>

The cros_ec_i2c driver is still active after it had suspended or before it
resumes. Besides that, it also tried to transfer data even after the I2C
host had been suspended. This leads the system to crash.

During the test, we also observed that the EC needs to be resumed
earlier due to some status polling from the EC firmware (e.g. battery
status). This patch moves the PM ops to late stage to make it work
normally.
