[PATCH] regulator: core: Remove "ramp_delay not set" debug message

["Christian Kohlschütter" <christian@kohlschutter.com>]

This message shows up occasionally but in bursts (seen as up 30 times
per second on my ODROID N2+).

According to Matthias Kaehlcke's comment in 'regulator: core: silence
warning: "VDD1: ramp_delay not set"', this message should have been
removed after restructuring previous code that assumed that ramp_delay
being zero in that function was an error.
