Florian Fainelli 80f697b57f MIPS: vdso: Utilize __pa() for gic_pfn ...

[ Upstream commit 8baa65126e ]

The GIC user offset is mapped into every process' virtual address and is
therefore part of the hot-path of arch_setup_additional_pages(). Utilize
__pa() such that we are more optimal even when CONFIG_DEBUG_VIRTUAL is
enabled, and while at it utilize PFN_DOWN() instead of open-coding the
right shift by PAGE_SHIFT.
