Unused code: Dead nested assignment
riscv.c:459 Although the value stored to 'ir_user4_raw' is
used in the enclosing expression, the value is
never actually read from 'ir_user4_raw'
This is caused by the value reassigned in 'ir_user4_raw':
riscv.c:459 ir_user4[3] = (uint8_t)(ir_user4_raw >>= 8);
but never used.
Drop the DIY conversion in favor of h_u32_to_le() that does not
reassign the input value.
