MIPS: vdso: Utilize __pa() for gic_pfn
[ Upstream commit 8baa65126e19af5ee9f3c07e7bb53da41c39e4b1 ]
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.
