Vivian Wang 43169328c7 lib/crypto: riscv/chacha: Avoid s0/fp register 
In chacha_zvkb, avoid using the s0 register, which is the frame pointer,
by reallocating KEY0 to t5. This makes stack traces available if e.g. a
crash happens in chacha_zvkb.

No frame pointer maintenance is otherwise required since this is a leaf
function.
