regulator: arizona-micsupp: Move pdata into a separate structure
In preparation for sharing this driver with Madera, move the pdata for the micsupp regulator out of struct arizona_pdata into a dedicated pdata struct for this driver. As a result the code in arizona_micsupp_of_get_pdata() can be made independent of struct arizona. This patch also updates the definition of struct arizona_pdata and the use of this pdata in mach-crag6410-module.c Signed-off-by: Richard Fitzgerald <rf@opensource.wolfsonmicro.com> Acked-by: Lee Jones <lee.jones@linaro.org> Signed-off-by: Mark Brown <broonie@kernel.org>
