drm/i915/gem: Use the correct format specifier for resource_size_t

Commit 05da7d9f ("drm/i915/gem: Downgrade stolen lmem setup
warning") adds a debug message where the "lmem_size" and
"dsm_base" variables are printed using the %lli identifier.

However, these variables are defined as resource_size_t, which
are unsigned long for 32-bit machines and unsigned long long for
64-bit machines.

The documentation (core-api/printk-formats.rst) recommends using
the %pa specifier for printing addresses and sizes of resources.

Replace %lli with %pa.

This patch also mutes the following sparse warning when compiling
with:

   make W=1 ARCH=i386 drivers/gpu/drm/i915

>> drivers/gpu/drm/i915/gem/i915_gem_stolen.c:941:5: error: format '%lli'
   expects argument of type 'long long int', but argument 5 has type
   'resource_size_t' {aka 'unsigned int'} [-Werror=format=]
