MPC85xx: TQM8548: use cache for AG and BE variants
This patch makes accesses to the system memory cachable by removing the caching-inhibited and guarded flags from the relevant TLB entries for the TQM8548_BE and TQM8548_AG modules. FYI, the Freescale MPC85* boards are configured similarly. This results in a big averall performace improvement. TFTP downloads, NAND Flash accesses, kernel boots, etc. are much faster.
