[PATCH v3 2/3] phy: qcom-snps-femto-v2: add system sleep PM ops

[Adrien Thierry <athierry@redhat.com>]

The downstream driver [1] implements set_suspend(), which deals with
both runtime and system sleep/resume. The upstream driver already has
runtime PM ops, so add the system sleep PM ops as well, reusing the same
code as the runtime PM ops.
