[PATCH v4 10/12] mfd: da9063: Register RTC only on DA9063L

[Marek Vasut <marek.vasut@gmail.com>]

The DA9063L does not contain RTC block, unlike the full DA9063.
Split the RTC block into separate mfd cell and register it only
on DA9063.

V2: No change
V3: Rework of mfd: da9063: Disallow RTC on DA9063L
V4: - Change the original failure text
    - Use PLATFORM_DEVID_NONE in mfd_add_devices
