[PATCH -next] phy: tegra: xusb: Make two functions static

[Yue Haibing]

From: YueHaibing <yuehaib...@huawei.com>

Fix sparse warning:

drivers/phy/tegra/xusb-tegra186.c:250:6: warning: symbol 
'tegra_phy_xusb_utmi_pad_power_on' was not declared. Should it be static?
drivers/phy/tegra/xusb-tegra186.c:281:6: warning: symbol 
'tegra_phy_xusb_utmi_pad_power_down' was not declared. Should it be static?
