[PATCH v2] phy: qcom-snps: Add runtime suspend and resume handlers

[PATCH v2] phy: qcom-snps: Add runtime suspend and resume handlers

[Wesley Cheng]

Allow for the PHY to be put into a powered down state when possible.
Add the required suspend and resume callbacks, which will determine
what resources can be turned off depending on the cable status.

Signed-off-by: Wesley Cheng <wcheng@codeaurora.org>

---
Changes in v2:
 - Addressed checkpatch alignment/line length warnings.
 - Removed superfluous init in qcom_snps_hsphy_resume().

Am still not convinced why this would be called when we are already
suspended :)

Remove debug artifacts here?

Lets align the lines above to opening brace please..
If you run checkpatch with --strict option you would get this CHECK: Alignment should match open parenthesis

This should be a separate patch, whats set_mode got to do with suspend
support :)

Hi Vinod,

OK, we can remove it for now, and if its really required further on, we
can re-add.
