RISC-V: Ensure kernel stack is aligned

Authored by jrtc27 on Dec 29 2019, 10:00 PM.



Currently, PCB_SIZE is an odd number of 8 bytes, as is 40, the size of
riscv_bootparams, so we happen to have an aligned kernel stack. Instead
we should round the allocation up as required. We can also fold the two
together to avoid unnecessarily padding each.
