hw/timer/aspeed: Fix interrupt status does not be cleared for AST2600
According to the datasheet of AST2600 description, interrupt status set by HW
and clear to "0" by software writing "1" on the specific bit.
Therefore, if firmware set the specific bit "1" in the interrupt status
register(0x34), the specific bit of "s->irq_sts" should be cleared 0.
