The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
To convert all those qcom pinctrl drivers, make msm_pinctrl_remove()
return void (instead of zero) and use .remove_new in all drivers.

interrupt targets
SA8775 and newer target have added support for an increased number of
interrupt targets. To implement this change, the intr_target field, which
is used to configure the interrupt target in the interrupt configuration
register is increased from 3 bits to 4 bits.
In accordance to these updates, a new intr_target_width member is
introduced in msm_pingroup structure. This member stores the value of
width of intr_target field in the interrupt configuration register. This
value is used to dynamically calculate and generate mask for setting the
intr_target field. By default, this mask is set to 3 bit wide, to ensure
backward compatibility with the older targets.

The SA8775P TLMM driver is missing the GPIO-to-wakeup-pin mapping. This
adds it.

Remove the msm_function struct to reuse the generic pinfunction
struct. Also, define a generic PINFUNCTION macro that can be used across
qcom target specific pinctrl files to avoid code repetition.
