Change subject: arch-riscv: Fix reset function and style

arch-riscv: Fix reset function and style
In addition to fixing some style issues with resetting, this patch fixes
what happens on reset. The RISC-V privileged ISA reference manual says
that,
on reset:
1. Privilege mode is set to M
2. mstatus.mie <- 0; mstatus.mprv <- 0
3. PC <- reset vector
4. mcause <- reset cause (0 if there is no distinguishing causes)
5. Everything else is undefined
Because of 5, everything else will be left alone
