gpio: pl061: delete platform data handling
Platform data is a remnant of board files and all boards using the PL061 have been migrated to use device tree or ACPI instead. The custom mechanism to set line by default as inputs/outputs has been superceded by the GPIO-internal hogging mechanism. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
