[PATCH 4/9] mtd: rawnand: brcmnand: Move OF operations out of brcmnand_init_cs()

From: Florian Fainelli
Date: Wed Dec 22 2021 - 19:22:48 EST


In order to initialize a given chip select object for use by the
brcmnand driver, move all of the Device Tree specific routines outside
of brcmnand_init_cs() in order to make it usable in a platform data
configuration which will be necessary for supporting BCMA chips.
