gpu: nvgpu: manage phys pages at runtime

Current implementation is based on config GK20A_PHYS_PAGE_TABLES
to have APIs to create/free/map/unmap phys pages

Remove this config based implementaion and move the APIs so that
they are called at runtime based on tegra_platform_is_linsim()

In generic APIs, we first check if platform is linsim and if it
is then we forward the call to phys page specific APIs
