pinctrl: bcm2835: Use define directive for BCM2835_PINCONF_PARAM_PULL
Clang warns when one enumerated type is implicitly converted to another: drivers/pinctrl/bcm/pinctrl-bcm2835.c:707:40: warning: implicit conversion from enumeration type 'enum bcm2835_pinconf_param' to different enumeration type 'enum pin_config_param' [-Wenum-conversion] configs[0] = pinconf_to_config_packed(BCM2835_PINCONF_PARAM_PULL, pull); ~~~~~~~~~~~~~~~~~~~~~~~~ ^~~~~~~~~~~~~~~~~~~~~~~~~~ 1 warning 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.
