[PATCH 11/51] phy: tegra: mark tegra_xusb_lane_lookup_function() static

[Kishon Vijay Abraham I]

From: Baoyou Xie <baoyou.xie@xxxxxxxxxx>

We get 1 warning when building kernel with W=1:
drivers/phy/tegra/xusb.c:104:5: warning: no previous prototype for 'tegra_xusb_lane_lookup_function' [-Wmissing-prototypes]

In fact, this function is only used in the file in which it is
declared and don't need a declaration, but can be made static.
So this patch marks it 'static'.
