Subject: [PATCH v3 3/9] mtd: rawnand: brcmnand: Avoid pdev in brcmnand_init_cs()

In preparation for encapsulating more of what the loop calling
brcmnand_init_cs() does, avoid using platform_device when it is the
device behind platform_device that we are using for printing errors.

No functional changes introduced.
