9485f8b6a7 x86/platform/atom/punit: Enable support for Merrifield
Intel Merrifield platform has Punit generation that somehow compatible to what
is already supported by punit_atom_debug driver.

Add necessary bits to enable that support.

4077a387b7 x86/platform/iosf_mbi: Remove duplicate definitions
The read and write opcodes are global for all units on SoC and even across
Intel SoCs. Remove duplication of corresponding constants. At the same time
convert all current users.

No functional change.

e971aa2cba x86/platform: Make atom/pmc_atom.c explicitly non-modular
The Kconfig currently controlling compilation of this code is:

config PMC_ATOM
        def_bool y

...meaning that it currently is not being built as a module by
anyone.

Lets remove the couple traces of modularity so that when reading
the driver there is no doubt it is builtin-only.

Since module_init() translates to device_initcall() in the
non-modular case, the init ordering remains unchanged with this
commit.

We leave some tags like MODULE_AUTHOR() for documentation
purposes.

Also note that MODULE_DEVICE_TABLE() is a no-op for non-modular
code. We correct a comment that indicates the data was only used
by that macro, as it actually is used by the code directly.

91780c41a9 x86/platform/intel/pmc_atom: Move the PMC-Atom code to arch/x86/platform/atom
This is specific driver for Intel Atom SoCs like BayTrail and
Braswell. Let's move it to dedicated folder and alleviate a
arch/x86/kernel burden.

There is no functional change.

956079e081 x86/platform/atom/punit: Add Punit device state debug driver
The patch adds a debug driver, which dumps the power states
of all the North complex (NC) devices. This debug interface is
useful to figure out the devices,  which blocks the S0ix
transitions on the platform. This is extremely useful during
enabling PM on customer platforms and derivatives.

This submission is based on the submission from Mahesh Kumar P:
