RISC-V: remove INTERRUPT_CAUSE_* defines from asm/irq.h
These are only of use to the local irq controller driver, so add them in
that driver implementation instead, which will be submitted soon.

RISC-V: simplify software interrupt / IPI code
Rename handle_ipi to riscv_software_interrupt, drop the unused return
value and move the prototype to irq.h together with riscv_timer_interupt.
This allows simplifying the upcoming interrupt handling support.

6d60b6ee0c RISC-V: Device, timer, IRQs, and the SBI
This patch contains code that interfaces with devices that are mandated
by the RISC-V supervisor specification and that don't have explicit
drivers anywhere else in the tree.  This includes the staticly defined
interrupts, the CSR-mapped timer, and virtualized SBI devices.
