[PATCH i-g-t v8 5/6] lib/xe/xe_util: Align obj size before bind/unbind

[Akshata Jahagirdar]

For 512 x 512 x 32pp, the ccs size comes to 2048B.
This size of surf-ctrl-copy smaller than page size
isn't properly handled in the blitter library code.
To address this issue, align the size to 4096 before vm bind/unbind operation.
