[RESEND PATCH v4 1/9] mm: Introduce new vm_map_pages() and vm_map_pages_zero() API

Previouly drivers have their own way of mapping range of kernel pages/memory into user vma and this was done by invoking vm_insert_page() within a loop. As this pattern is common across different drivers, it can be generalized by creating new functions and use it across the drivers.
