mainlining shenanigans

We currently get the following error with pixcir_ts driver during a suspend resume cycle: omap_i2c 4802a000.i2c: controller timed out pixcir_ts 1-005c: pixcir_int_enable: can't read reg 0x34 : -110 pixcir_ts 1-005c: Failed to disable interrupt generation: -110 pixcir_ts 1-005c: Failed to stop dpm_run_callback(): pixcir_i2c_ts_resume+0x0/0x98 [pixcir_i2c_ts] returns -110 PM: Device 1-005c failed to resume: error -110 And at least am437x based devices with pixcir_ts will fail to resume to a touchscreen that is configured as the wakeup-source in device tree for these devices. This is because pixcir_ts tries to reconfigure it's registers for noirq suspend which fails. This also leaves i2c-omap in enabled state for suspend. Let's fix the pixcir_ts issue and make sure i2c-omap is suspended by adding SET_NOIRQ_SYSTEM_SLEEP_PM_OPS. Let's also get rid of some ifdefs while at it and replace them with __maybe_unused as SET_RUNTIME_PM_OPS and SET_NOIRQ_SYSTEM_SLEEP_PM_OPS already deal with the various PM Kconfig options.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
