In preparation for removing HANDLE_DOMAIN_IRQ_IRQENTRY, have arch/riscv perform all the irqentry accounting in its entry code. As arch/riscv uses GENERIC_IRQ_MULTI_HANDLER, we can use generic_handle_arch_irq() to do so. Since generic_handle_arch_irq() handles the irq entry and setting the irq regs, and happens before the irqchip code calls handle_IPI(), we can remove the redundant irq entry and irq regs manipulation from handle_IPI(). There should be no functional change as a result of this patch.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
