Kernel (for ppgtt) requires memory address to be aligned to page size (4096). Added such alignment for buffers marked with EXEC_OBJECT_PINNED.
-v2: added marking that also fixes initial commit 01058a552294 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=106997 Fixes: a363bb2cd0e2 (i965: Allocate VMA in userspace for full-PPGTT systems.) Fixes: 01058a552294 (i965: Add virtual memory allocator infrastructure to brw_bufmgr.)
