Subject[PATCH v5 12/14] mfd: da9063: Register RTC only on DA9063L
Date
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
V5: Rebase on top of new 01 and 02 patches
