Subject: [PATCH 1/4] mfd: cs5535-mfd: Use PLATFORM_DEVID_* defines and tidy error message

In most contexts '-1' doesn't really mean much to the casual observer.
In almost all cases, it's better to use a human readable define.  In
this case PLATFORM_DEVID_* defines have already been provided for this
purpose.

While we're here, let's be specific about the 'MFD devices' which
failed.  It will help when trying to distinguish with of the 2 sets of
sub-devices we actually failed to register.
