qemu: update arm timer handling
commit
e388771458b4ff3ad81ab70e390b24d069647da4 in the upstream
kernel factored/cleaned the SP804 timer code. This commit exposed
issues in the qemu timer emulation that was dependent on the
old behaviour. As a result, no kernel past 2.6.34 would boot on
qemu-system-arm.
The quick fix is to backport two patches from the latest qemu
repositories that fix the timer handling under emulation. Long
term, these will be dropped when qemu is upreved.
