ar71xx: mach-rbspi: fix 74x164 support
The platform data was missing the num_registers element which is now mandatory in linux 4.9 Without this patch, the gpio probing would fail with: gpio gpiochip1: (74x164): tried to insert a GPIO chip with zero lines Fixes: #1106 Tested-by: Robert Marko <robimarko@gmail.com> Signed-off-by: Thibaut VARENE <hacks@slashdirt.org>
