[PATCH] dell-laptop: depends on POWER_SUPPLY

[Randy Dunlap]

From: Randy Dunlap <randy.dunlap@xxxxxxxxxx>

Build breaks when DELL_LAPTOP=y and POWER_SUPPLY=m. DELL_LAPTOP needs
to depend on POWER_SUPPLY.

dell-laptop.c:(.text+0x1ef3c4): undefined reference to `power_supply_is_system_supplied'
dell-laptop.c:(.text+0x1ef45e): undefined reference to `power_supply_is_system_supplied'
