Convert 'pwm_chip_to_gb_pwm_chip' from a macro to a static
inline function, to make the relevant types apparent in the
definition and to benefit from the type checking performed by
the compiler at call sites.

Since commit f9a8ee8c8b ("pwm: Always allocate PWM chip base ID
dynamically") the value held in base isn't used any more in the PWM
framework. All PMWs get assigned a dynamic ID, so the assignment is
redundant and can be dropped.

Now that the SPDX tag is in all greybus files, that identifies the
license in a specific and legally-defined manner. So the extra GPL text
wording can be removed as it is no longer needed at all.
This is done on a quest to remove the 700+ different ways that files in
the kernel describe the GPL license text. And there's unneeded stuff
like the address (sometimes incorrect) for the FSF which is never
needed.
No copyright headers or other non-license-description text was removed.

It's good to have SPDX identifiers in all files to make it easier to
audit the kernel tree for correct licenses.
Update the drivers/staging/greybus files files with the correct SPDX
license identifier based on the license text in the file itself. The
SPDX identifier is a legally binding shorthand, which can be used
instead of the full boiler plate text.
This work is based on a script and data from Thomas Gleixner, Philippe
Ombredanne, and Kate Stewart.

In the 4.7-rc1 kernel release, PWMF_ENABLED is removed and
pwm_is_enabled() is the correct way to test if a pwm device is enabled,
so provide a version of that function that will work on all older
kernels and change the pwm.c driver to use it so that it will work on
newer kernels as well.
Tested:

of at protocol level for bridged PHY devices as well.
The bundle version handling is already in place, though it is *not* used
today as we haven't bumped the version of control protocol yet.
