[PATCH] drm/ttm_bo_api: update the description for @placement and @sg

[Amos Kong]

Correct the argument name of @placement and added @sg description for
ttm_bo_init() and ttm_bo_init_reserved().

Argument @flags was replaced to @placement by Jerome in commit
09855acb1c2e3779f25317ec9a8ffe1b1784a4a8

Argument @sg was added by Dave in commit
129b78bfca591e736e56a294f0e357d73d938f7e
