rtc: sh: assign correct interrupts with DT

[ Upstream commit 8f2efdbc303fe7baa83843d3290dd6ea5ba3276c ]

The DT bindings for this driver define the interrupts in the order as
they are numbered in the interrupt controller. The old platform_data,
however, listed them in a different order. So, for DT based platforms,
they are mixed up. Assign them specifically for DT, so we can keep the
bindings stable. After the fix, 'rtctest' passes again on the Renesas
Genmai board (RZ-A1 / R7S72100).
