[U-Boot] [PATCH] Fix compilation warnings when building eNET

[Vadim Bendebury]

There have been a couple of unused variable cases, causing compilation
warnings when building the eNET target.

While the board/eNET/eNET.c:last_stage_init() case seems a leftover
from a quick edit, the arch/x86/cpu/sc520/sc520_timer.c:sc520_udelay()
seems to actually require accessing the registers discarding the
values.

The source code is being modified accordingly.

TEST:
 - the eNET target now builds cleanly
 - examining disassembled sc520_timer.o shows that the registers are
   still being accessed in the beginning of the function.
