It is introduced for the pre-0.96 xHC controllers, and the driver only
support HW LPM for 1.0 and later controllers.It's not actually used now
and is thought not to be used in the future any more, so just remove it.

Allowing too long exit latencies for periodic endpoint confuses xHC

Hi Greg
These two patches are part 2/5 and 3/5 of the Tegra xhci genpd
support series.
It's how Jon Hunter proposed them to be merged:
" This series is making changes to more than one subsystem and at first
glance may look like a maintainers nightmare. However, my proposal is
this, once
' property is present and otherwise we fall back to
using the legacy Tegra APIs for managing the power-domains.
