pinctrl: dra: dt-bindings: Fix output pull up/down

For PIN_OUTPUT_PULLUP and PIN_OUTPUT_PULLDOWN we must not set the
PULL_DIS bit which disables the PULLs.

PULL_ENA is a 0 and using it in an OR operation is a NOP, so don't
use it in the PIN_OUTPUT_PULLUP/DOWN macros.

Fixes: 23d9cec0 ("pinctrl: dra: dt-bindings: Fix pull enable/disable")
