arm: tegra: power: add pcie dependency to xusb ops
Due to a HW bug 1320346 in t12x/t13x, PCIE needs to be unpowergated when XUSB
is to be accessed. Currently PCIE powergating ops need to be invoked from XUSB
driver since powergating module doesn't internally handle this dependency.
This patch implements this dependency within the powergating module so that
xhci-tegra driver can stay chip-agnostic.
