[PULL 11/50] target/riscv: use RISCVException enum in exception helpers

[Alistair Francis]

From: Daniel Henrique Barboza <dbarboza@ventanamicro.com>

Do a cosmetic change in riscv_raise_exception() to change 'exception'
type from uint32_t to RISCVException, making it a bit clear that the
arg is directly correlated to the RISCVException enum.

As a side effect, change 'excp' type from int to RISCVException in
generate_exception() to guarantee that all callers of
riscv_raise_exception() will use the enum.
