vdso: Use CONFIG_PAGE_SHIFT in vdso/datapage.h
Both the vdso rework and the CONFIG_PAGE_SHIFT changes were merged during
the v6.9 merge window, so it is now possible to use CONFIG_PAGE_SHIFT
instead of including asm/page.h in the vdso.
This avoids the workaround for arm64 - commit 8b3843ae3634 ("vdso/datapage:
Quick fix - use asm/page-def.h for ARM64") and addresses a build warning
for powerpc64:
