Currently the space between kernel_addr_r and the fdt_addr_r is only 32MB. To have enough space to load kernel images bigger than 32MB change the variables to a feasible value.

The new environment variables layout is based on the scheme from "include/configs/ti_armv7_common.h".

The CONFIG_SYS_LOAD_ADDR value is set to 0x42000000. With that we have the same value as for the kernel_addr_r.
