nocturne: switch from tablet mode to base state reporting

On these devices we can't decide whether we should go in/out tablet mode
solely because base was attached or detached. Let's report the new "base
attached" event so that upper layers can figure the state properly.

Note that we disable CONFIG_DPTF_DEVICE_ORIENTATION switch since it
requires CONFIG_TABLET mode which we disable as well. That means that
EC_ACPI_MEM_DEVICE_ORIENTATION will always return '0', which should be
fine, as it is used by the TBMC (Tablet Motion Control) device which is
not enabled on Nocturne. Note that base attach/detach events, like
tablet mode switch events, will still wake up the AP as handles base
state transitions always notifies host of attach/detach events.
