mfd: intel-lpss: Move linux/pm.h to the local header
We now using a common macro for PM operations in Intel LPSS driver,
and, since that macro relies on the definition and macro from linux/pm.h
header file, it's logical to include it directly in intel-lpss.h.
Otherwise it's a bit fragile and requires a proper ordering
of header inclusion in C files.

mfd: intel-lpss: Add default I2C device properties for Apollo Lake
Default I2C device properties for Intel Broxton, especially SDA hold time
may not be enough on Intel Apollo Lake. These properties are used in case
we don't get timing parameters from ACPI.
The default SDA hold time for Broxton may fail with arbitration lost errors
on Apollo Lake:
i2c_designware i2c_designware.1: i2c_dw_handle_tx_abort: lost arbitration
Fix this by using different default device properties on Apollo Lake than
Broxton.

Since device_add_property_set() now always takes a copy of
the property_set, and also since the fwnode type is always
hard coded to be FWNODE_PDATA, there is no need for the
drivers to deliver the entire struct property_set. The
function can just create the instance of it on its own and
bind the properties from the drivers to it on the spot.
This renames device_add_property_set() to
device_add_properties(). The function now takes struct
property_entry as its parameter instead of struct

mfd: intel-lpss: Pass SDA hold time to I2C host controller driver
Intel Skylake the LPSS I2C pad circuit has internal delays that require
programming non-zero SDA hold time for the I2C host controller. If this is

errors like the one seen below taken from Lenovo Yoga 900:

To fix this we follow what the Windows driver is doing and pass the default
SDA hold time of 230 ns to all Intel Skylake host controllers. This still
allows the platform to override these values by passing special ACPI
methods SSCN and FMCN.

We now using a common macro for PM operations in Intel LPSS driver,

header file, it's logical to include it directly in intel-lpss.h.
Otherwise it's a bit fragile and requires a proper ordering

The default SDA hold time for Broxton may fail with arbitration lost errors
