rtc: bunch of drivers: fix 'no irq' case handing
This patch fixes a bunch of irq checking misuses. Most drivers were
getting irq via platform_get_irq(), which returns -ENXIO or r->start.
rtc-cmos.c is special. It is using PNP and platform bindings. Hopefully
nobody is using PNP IRQ 0 for RTC. So the changes should be safe.
rtc-sh.c is using platform_get_irq, but was storing a result into an
unsigned type, then was checking for < 0. This is fixed now.
