MLK-11044: mtd:nand: enable per1_bch for NAND on all i.MX6 platform
The per1_bch was moved in patch below since it was never mentioned in
any GPMI/BCH/APBH documents, but actually it is necessary for BCH module
since BCH use AXI bus transfer data through fabric, need to enable this
clock for BCH at fabric side.
This patch enabled this clock for all i.MX6 platforms and has been
tested on i.MX6Q/i.MX6QP/i.MX6SX and i.MX6UL.

mtd: nand: support NAND on i.MX6UL

per1_bch.
