Subject: [PATCH] regulator: core: Stub devm_regulator_bulk_get_const() if !CONFIG_REGULATOR

When adding devm_regulator_bulk_get_const() I missed adding a stub for
when CONFIG_REGULATOR is not enabled. Under certain conditions (like
randconfig testing) this can cause the compiler to reports errors
like:

  error: implicit declaration of function 'devm_regulator_bulk_get_const';
  did you mean 'devm_regulator_bulk_get_enable'?

Add the stub.

Fixes: 1de452a0edda ("regulator: core: Allow drivers to define their init data as const")
