regulator: arizona-ldo1: Move pdata into a separate structure

In preparation for sharing this driver with Madera, move the pdata
for the LDO1 regulator out of struct arizona_pdata into a dedicated
pdata struct for this driver. As a result the code in
arizona_ldo1_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
