dt-bindings: mtd: brcmnand: Add ecc strap property 



Add brcm,nand-ecc-use-strap to get ecc and spare area size settings from
board boot strap for broadband board designs because they do not specify
ecc setting in dts but rather using the strap setting.

        description:

          This property requires the host system to get the ECC related

          settings from the SoC NAND boot strap configuration instead of

          the generic NAND ECC settings. This is a common hardware design

          on BCMBCA based boards. This strap ECC option and generic NAND

          ECC option can not be specified at the same time.
