ARM: tegra: enable Ardbeg USB2 UHSIC PHY wakeup
Icera Bruce modem is using tegra_ehci2_device on t124 Ardbeg with HSIC
phy, so enable USB2 UHSIC PHY wakeup source so that remote wakeup can
work in LP0.
Also add a generic function tegra_set_wake_source() in wakeups-t12x.c,
which can be used to modify tegra_wake_event_irq table from board files.
