[U-Boot] [RFC] arm926ejs: fix jump to RAM nand_boot

[Albert Aribaud]

RFC again. WARNING -- apply *above* the previous one, not instead!

I *think* the current jump to nand_boot was wrong, because it
loads an offset but does not add it to the relocated base before
jumping to it. I thus applied the same sequence as board_init_r.

Wolfgang, please test to see if tx25 works with this.

Alexander, Darius, others who already tested the previous RFC patch,
please test for non-regression.

Amicalement,
Albert.
