power: rt9455: hide unused rt9455_boost_voltage_values
[ Upstream commit 452d8950db3e839aba1bb13bc5378f4bac11fa04 ]
The rt9455_boost_voltage_values[] array is only used when USB PHY
support is enabled, causing a W=1 warning otherwise:
drivers/power/supply/rt9455_charger.c:200:18: error: 'rt9455_boost_voltage_values' defined but not used [-Werror=unused-const-variable=]
Enclose the definition in the same #ifdef as the references to it.
Fixes: e86d69dd786e ("power_supply: Add support for Richtek RT9455 battery charger")
