drm/radeon: refactor set_page chipset interface v5
Cleanup the interface in preparation for hierarchical page tables.
v2: add incr parameter to set_page for simple scattered PTs uptates
added PDE-specific flags to r600_flags and radeon_drm.h
removed superfluous value masking with 0xffffffff
v3: removed superfluous bo_va->valid checking
changed R600_PTE_VALID to R600_ENTRY_VALID to handle PDE too
v4 (ck): fix indention style, rework and fix typos in commit message,
add documentation for incr parameter, also use incr
parameter for system pages
v5 (agd5f): use upper_32_bits() and minor white space fixes
