[PATCH 0/2] Not to clear all the bits of mip

[Nick Hu]

In generic behavior of QEMU, if we clear the mip.SEIP and the pendings of
PLIC still exist, the QEMU may not set the mip.SEIP back immediately. So
interrupts won't be handled anymore until the next new device interrupt
arrived. We should only clear the SSIP and STIP which set by SW. The rest
of the bits should be decided by HW.
