[U-Boot] [PATCH 2/2] Fix compile errors for atmel_nand with hw-ecc and new SoC access

[Alexander Holler <holler@ahsoftware.de>]

atmel_nand.c with HW-ECC doesn't compile with the new SoC access.
Using CONFIG_AT91_LEGACY to circumvent the compile errors only leaves
the driver in a state where it doesn't find the NAND.

To use HW-ECC with atmel_nand one has to use
CONFIG_SYS_NAND_ECC_BASE AT91_ECC0_BASE (instead of AT91_ECC0)
for an AT91SAM9263 or AT91_ECC_BASE for an AT91SAM9260.

I've removed three unused variables too.
