Alex Smith c0a9f72c15 irqchip: irq-mips-gic: Provide function to map GIC user section
The GIC provides a "user-mode visible" section containing a mirror of
the counter registers which can be mapped into user memory. This will
be used by the VDSO time function implementations, so provide a
function to map it in.

When the GIC is not enabled in Kconfig a dummy inline version of this
function is provided, along with "#define gic_present 0", so that we
don't have to litter the VDSO code with ifdefs.

[markos.chandras@imgtec.com:
  - Move mapping code to arch/mips/kernel/vdso.c and use a resource
    type to get the GIC usermode information
  - Avoid renaming function arguments and use __gic_base_addr to hold
    the base GIC address prior to ioremap.]
[ralf@linux-mips.org: Fix up gic_get_usm_range() to compile and make inline
again.]
