[U-Boot] [PATCH] gpio: zynq: Read of mach data in platdata with dev_get_driver_data

[Michal Simek]

Remove bogus zynq_gpio_getplat_data() and read driver data directly.

Signed-off-by: Michal Simek <michal.simek at xilinx.com>

Driver should use platdata structure but this change should be fine
before this is fixed.
Simon: Is ofdata_to_platdata correct function where this should be read?
