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

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.
