[U-Boot] [PATCH v4] mx31ads: Use the new relocation scheme

[Fabio Estevam]

This fixes the MX31ADS build by using the new relocation scheme.

Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com>
Tested-by: Felix Radensky <felix@embedded-sol.com>
---
Changes since v3:
- Fix CONFIG_SYS_TEXT_BASE and boot is confirmed to work now
Changes since v2:
- Use PHYS_SDRAM_1 in get_ram_size
- Remove local config.mk
Changes since v1:
- Fixed lines over 80 characters.
