pinctrl: lpc18xx: Use define directive for PIN_CONFIG_GPIO_PIN_INT
Clang warns when one enumerated type is implicitly converted to another: drivers/pinctrl/pinctrl-lpc18xx.c:643:29: warning: implicit conversion from enumeration type 'enum lpc18xx_pin_config_param' to different enumeration type 'enum pin_config_param' [-Wenum-conversion] {"nxp,gpio-pin-interrupt", PIN_CONFIG_GPIO_PIN_INT, 0}, ~ ^~~~~~~~~~~~~~~~~~~~~~~ drivers/pinctrl/pinctrl-lpc18xx.c:648:12: warning: implicit conversion from enumeration type 'enum lpc18xx_pin_config_param' to different enumeration type 'enum pin_config_param' [-Wenum-conversion] PCONFDUMP(PIN_CONFIG_GPIO_PIN_INT, "gpio pin int", NULL, true), ~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ./include/linux/pinctrl/pinconf-generic.h:163:11: note: expanded from macro 'PCONFDUMP' .param = a, .display = b, .format = c, .has_arg = d \ ^ 2 warnings generated. It is expected that pinctrl drivers can extend pin_config_param because of the gap between PIN_CONFIG_END and PIN_CONFIG_MAX so this conversion isn't an issue. Most drivers that take advantage of this define the PIN_CONFIG variables as constants, rather than enumerated values. Do the same thing here so that Clang no longer warns.
