The zynq and qcom-spmi pinctrl drivers both use pin_config_item arrays
to provide extra interfaces in debugfs. This structure and the
PCONFDUMP macro are not defined if CONFIG_DEBUG_FS is turned off,
so we get build errors like:

pinctrl/qcom/pinctrl-spmi-gpio.c:139:37: error: array type has incomplete element type
 static const struct pin_config_item pmic_conf_items[ARRAY_SIZE(pmic_gpio_bindings)] = {
                                     ^
pinctrl/qcom/pinctrl-spmi-gpio.c:140:2: error: implicit declaration of function 'PCONFDUMP' [-Werror=implicit-function-declaration]
  PCONFDUMP(PMIC_GPIO_CONF_PULL_UP,  "pull up strength", NULL, true),
  ^
pinctrl/qcom/pinctrl-spmi-gpio.c:139:37: warning: 'pmic_conf_items' defined but not used [-Wunused-variable]
 static const struct pin_config_item pmic_conf_items[ARRAY_SIZE(pmic_gpio_bindings)] = {

Lacking any better idea to solve this nicely, this patch uses #ifdef
to hide the structures, just like the pinctrl core does.

New pin controllers such as ACPI-based may also have custom properties
to parse, and should be able to use generic pin config. Let's make the
code compile on !OF systems and rename members a bit to underscore it
is custom parameters and not necessarily DT parameters.

This fixes a build regression for x86_64 on the zeroday kernel builds.

Instead of the driver caring about implementation details like device
tree, just provide information about driver specific pinconf parameters
to pinconf-generic which takes care of parsing the DT.

This is the pinctrl, pinmux, pinconf and gpiolib driver for the
Qualcomm GPIO sub-function blocks found in the PMIC chips.
