TQM85xx: NAND support via local bus UPMB

Browse source 
This patch adds support for NAND FLASH on the TQM8548. It is disabled by
default and can be enabled for the TQM8548 modules. It is now based on
the re-written FSL NAND UPM driver. A patch has been posted earlier today
with the subject:

"NAND FSL UPM: driver re-write using the hwcontrol callback"

Note that the R/B pin is not supported by that module requiring to use
the specified maximum delay time.

Note: With NAND support enabled the size of the U-Boot image exceeds
256 KB and TEXT_BASE must therefore be set to 0xfff80000 in config.mk,
doubling the image size :-(.
