parisc: increase kernel stack size to 32k
This commit temporarily increases the kernel stack size to 32k to avoid
stack overflows which led to strange and hard-to-debug kernel crashes
all over various kernel components.
The upcoming real fix will implement an own irq stack which should avoid
those crashes without the need for 32k stacks.
