[PATCH] drm/amd/display: use GFP_ATOMIC for bounding box

[Alex Deucher]

This can be called in atomic context.  Should fix:

BUG: sleeping function called from invalid context at include/linux/sched/mm.h:306
in_atomic(): 1, irqs_disabled(): 0, non_block: 0, pid: 449, name: kworker/u64:8
preempt_count: 2, expected: 0
RCU nest depth: 0, expected: 0
Preemption disabled at:
ffffffffc0ce1580>] dc_fpu_begin+0x30/0xd0 [amdgpu]
CPU: 5 PID: 449 Comm: kworker/u64:8 Tainted: G        W          6.8.0+ #35
Hardware name: System manufacturer System Product Name/ROG STRIX X570-E GAMING WIFI II, BIOS 4204 02/24/2022
Workqueue: events_unbound async_run_entry_fn
