ARM: pxa: irq: fix handling of ICMR registers in suspend/resume
[ Upstream commit 0c1049dcb4ceec640d8bd797335bcbebdcab44d2 ]
PXA3xx platforms have 56 interrupts that are stored in two ICMR
registers. The code in pxa_irq_suspend() and pxa_irq_resume() however
does a simple division by 32 which only leads to one register being
saved at suspend and restored at resume time. The NAND interrupt
setting, for instance, is lost.
Fix this by using DIV_ROUND_UP() instead.
