[PATCH] HID: steam: select CONFIG_POWER_SUPPLY

[Arnd Bergmann]

Using the power supply APIs requires selecting the appropriate
Kconfig symbol, otherwise we get this build failure:

drivers/hid/hid-steam.o: In function `steam_unregister':
hid-steam.c:(.text+0x1cc): undefined reference to `power_supply_unregister'
drivers/hid/hid-steam.o: In function `steam_battery_get_property':

hid-steam.c:(.text+0x13fe): undefined reference to `power_supply_powers'
