Subject: [PATCH v7 0/7] mfd: rn5t618: Add RTC/ADC support

In the variant RC5T619 the mfd has an RTC. This patchset adds
support for it. To do so it adds the missing register defines in 
rn5t618.h and general irq handling for that.
It seems that the IRQ definitions are the same except missing RTC
for the RN5T618 but due to missing ability to test that they are
not added here.
It also adds support for the ADC, it is available in both the
RN5T618 and RC5T619 but due to missing ability to test that,
the subdevice is only added for the RC5T619.

It was tested on the Kobo Clara HD.

Changes in v7:
- cleanup in IRQ init stuff

Changes in v6:
- put together with ADC series
- also added cleanup i2_device_id patch to avoid merge
  conflicts

Changes in v5:
- static rn5t618_irq_init
- PLATFORM_DEVID_NONE
- added some Acked-Bys

Changes in v4:
- use macros for IRQ definitions
- merge rn5t618-core.c and rn5t618-irq.c

Changes in v3:
- alignment cleanup
- output cleanup, remove useless toggling of alarm flag in rtc probe
- updated bindings description, so patch 1/5 becomes 2/6 and so on

Changes in v2:
- no dead code in irq code
- various improvements and cleanups in rtc driver itself
