[U-Boot] Nios2: bootm command bugs (lead to Kernel guzip "crc error" or "ran out of input data") and cfi_flash timeout error

I've tested u-boot 2009/03 with the last nios2 uClinux kernel and I've found 2 bugs (or things that can be changed to improve performance). => CFI "bug" The first bug is related to the Common Flash Interface handling code: the write/clear/etc.. timeout is calculated assuming a 1kHz timer tick
