ACPI: platform_profile: Add device pointer into platform profile handler
In order to let platform profile handlers manage platform profile
for their driver the core code will need a pointer to the device.
Add this to the structure and use it in the trivial driver cases.

ACPI: platform-profile: Add a name member to handlers
In order to prepare for allowing multiple handlers, introduce
a name field that can be used to distinguish between different
handlers.

The SSAM_DEFINE_SYNC_REQUEST_x() macros are intended to reduce
boiler-plate code for SSAM request definitions by defining a wrapper
function for the specified request. The client device variants of those
macros, i.e. SSAM_DEFINE_SYNC_REQUEST_CL_x() in particular rely on the
multi-device (MD) variants, e.g.:
#define SSAM_DEFINE_SYNC_REQUEST_CL_R(name, rtype, spec...) \
SSAM_DEFINE_SYNC_REQUEST_MD_R(__raw_##name, rtype, spec) \
int name(struct ssam_device *sdev, rtype *ret) \
{ \
return __raw_##name(sdev->ctrl, sdev->uid.target, \
sdev->uid.instance, ret); \
}
This now creates the problem that it is not possible to declare the
generated functions static via
static SSAM_DEFINE_SYNC_REQUEST_CL_R(...)
as this will only apply to the function defined by the multi-device
macro, i.e. SSAM_DEFINE_SYNC_REQUEST_MD_R(). Thus compiling with
`-Wmissing-prototypes' rightfully complains that there is a 'static'
keyword missing.
To solve this, make all SSAM_DEFINE_SYNC_REQUEST_x() macros define
static functions. Non-client-device macros are also changed for
consistency. In general, we expect those functions to be only used
locally in the respective drivers for the corresponding interfaces, so
having to define a wrapper function to be able to export this should be
the odd case out.

Add a driver to provide platform profile support on 5th- and later
generation Microsoft Surface devices with a Surface System Aggregator
Module. On those devices, the platform profile can be used to influence
cooling behavior and power consumption.
For example, the default 'quiet' profile limits fan noise and in turn
sacrifices performance of the discrete GPU found on Surface Books. Its
full performance can only be unlocked on the 'performance' profile.
