Add MFD support for the DA9063 OnKey driver
The function da9063_clear_fault_log() is added to mitigate the case of a
hardware power-cut after a long-long OnKey press. Although there is no
software intervention in this case (by definition) such a shutdown would
cause persistent information within the DA9063 FAULT_LOG that would be
available during the next device restart.
Clearance of this persistent register must be completed after such a
hardware power-cut operation has happened so that the FAULT_LOG does not
continue with previous values. The clearance function has been added here
in the kernel driver because wiping the fault-log cannot be counted on
outside the Linux kernel.

After registering mfd device with proper irq_base
platform_get_irq_byname() calls will return VIRQ instead of local IRQ.
This fixes da9063 rtc registration issue:

Add register definitions for DA9063 AD (0x3) silicon variant ID
the ability to choose the silicon variant at run-time using regmap
configuration. This patch also adds RTC support for the AD silicon
changes.
It adds both BB and AD support as regmap ranges and then makes the
distinction between the two tables at run-time. This allows both AD
and BB silicon variants to be supported at the same time.

Add the correct silicon variant code ID (0x5) to the driver. This
new code is the 'production' variant code ID for DA9063.
This patch will remove the older variant code ID which matches the
pre-production silicon ID (0x3) for the DA9063 chip.
There is also some small amount of correction done in this patch:
it splits the revision code and correctly names it according to
the hardware specification and moves the dev_info() call before
the variant ID test.

As of commit 03e361b25ee8dfb1fd9b890072c23c4aae01c6c7 ("mfd: Stop setting
refcounting pointers in original mfd_cell arrays"), the "cell" parameter of
mfd_add_devices() is "const" again. Hence make all cell data passed to
mfd_add_devices() const where possible.

This is MFD module providing access to registers and interrupts of DA906x
series PMIC. It is used by other functional modules, registered as MFD cells.
Driver uses regmap with paging to access extended register list. Register map
is divided into two pages, where the second page is used during initialisation.
This module provides support to following functional cells:
- Regulators
- RTC
- HWMON
- OnKey (power key misc input device)
- Vibration (force-feedback input device)
- Watchdog
- LEDs
