Subject: [PATCH v1] regulator: core: Convert warning to debug print

There are some boards without the vcc regulators for eeprom or other
devices. In such cases, we should not see the following warning and
this confuses the user. We want to see this only when it is compiled
with CONFIG_REGULATOR_DEBUG option.

[0.747347] at24 6-0055: supply vcc not found, using dummy regulator
[0.752877] pca953x 6-0074: supply vcc not found, using dummy regulator
