kernel/os/arch: Fix Cortex-M irq priority setting

For Cortex-M0:
os_arch_os_init() initialized interrupt priority level
for all interrupts using incorrect array limit taken
from sizeof instead of ARRAY_SIZE.
For Cortex-M0 field IP is array of uint32_t unlike all
other version where this array consist of uint8_t.

Now array is iterated using ARRAY_SIZE(NVIC->IP) to limit
instead of sizeof(NVIC->IP) and for Cortex-M33
ARRAY_SIZE(NVIC->IPR).
