Subject: [PATCH printk v4 04/39] printk: register_console: use "registered" for variable names

The @bootcon_enabled and @realcon_enabled local variables actually
represent if such console types are registered. In general there
has been a confusion about enabled vs. registered. Incorrectly
naming such variables promotes such confusion.

Rename the variables to _registered.
