Replace SET_LATE_SYSTEM_SLEEP_PM_OPS() with its modern
LATE_SYSTEM_SLEEP_PM_OPS() alternative.
The combined usage of pm_sleep_ptr() and LATE_SYSTEM_SLEEP_PM_OPS() allows
the compiler to evaluate if the runtime suspend/resume() functions
are used at build time or are simply dead code.
This allows removing the __maybe_unused notation from the runtime
suspend/resume() functions.

The previous pinconf settings(made by the bootloader) need to be
overwritten when configuring the pinctrl of a driver during the boot
process.
Configuring the bias of a GPIO at runtime (e.g. pull-up) needs to
preserve the other settings unaltered.
This patch introduces changes to differentiate between the two cases.

In the probe, if an error occurs after the ti_iodelay_pinconf_init_dev()
call, it is likely that ti_iodelay_pinconf_deinit_dev() should be called,
as already done in the remove function.
Also in ti_iodelay_pinconf_init_dev(), if an error occurs after the first
regmap_update_bits() call, it is also likely that the deinit() function
should be called.
The easier way to fix it is to add a devm_add_action_or_reset() at the
rigtht place to have ti_iodelay_pinconf_deinit_dev() called when needed.
Doing so, the .remove() function can be removed, and the associated
platform_set_drvdata() call in the probe as well.
