[U-Boot] [PATCH 4/5] MPC8308RDB: various clean ups

This patch cleans up the Freescale MPC8308RDB Development board support.
Things fixed:
- Removed unused PCIE2 definitions from configuration
- SICR{L,H} defines used for System I/O Configuration Registers values
instead of hardcoding
- CONFIG_SYS_SCCR_PCIEXP1CM used to enable PCIE clock instead of
writing to SCCR from the board code
- sleep mode stuff removed as MPC8308 has no support for deep sleep and
PMCCR1 register. board_early_init_f() removed.
- MPC8308 has no ERRATA for DDR controller so workaround removed
- 'assignment in if statement' issues solved
- use LBLAWAR_* defines instead of hardcoding
