regulator: core: Remove unused get_device_regulator

Browse Source 
commit 222cc7b1 (regulator: core: Allow multiple requests of a single supply mapping)
removed the usage of get_device_regulator().

Remove the function definition too amd get rid of the following warning:

drivers/regulator/core.c:112:26: warning: 'get_device_regulator' defined but not used [-Wunused-function]
