[U-Boot] [PATCH] arm: Do not clear LR on exception in SPL

[Andrew F. Davis]

When an exception or interrupt occurs the link register (LR) may
contain the source of the exception, although we do not print the
value it may still be extracted with a debugger. When in SPL we
loop on getting and exception, but use a linking branch, which
over-writes the LR value, use a regular branch instruction here.
