Subject: [PATCH v2 1/2] pinctrl: remove pinctrl/machine.h inclusion from pinctrl/pinconf.h

The change adds explicit inclusion of linux/pinctrl/machine.h header
to the only needed pinctrl-madera-core.c file, and therefore inclusion
of pinctrl/machine.h header from pinctrl/pinconf.h can be removed.

The change is preparatory to a follow-up reversal of commit f07512e615dd
("pinctrl/pinconfig: add debug interface").

Changes from v1 to v2:
* new change to mitigate a compile time warning caused by a removal of
  implicit header inclusion, the issue was reported against v1 change.

This change might be percepted as a bit awkward, but I leave a room to
extend it to other drivers, if it becomes needed. However apparently
only pinctrl/cirrus/pinctrl-madera-core.c misses explicit inclusion of
linux/pinctrl/machine.h header.
