drm/amdgpu/powerplay: fix sysfs_emit/sysfs_emit_at handling
sysfs_emit and sysfs_emit_at requrie a page boundary aligned buf address. Make them happy! v2: fix sysfs_emit -> sysfs_emit_at missed conversions Cc: Lang Yu <lang.yu@amd.com> Cc: Darren Powell <darren.powell@amd.com> Fixes: 6db0c87a0a8e ("amdgpu/pm: Replace hwmgr smu usage of sprintf with sysfs_emit") Bug: https://gitlab.freedesktop.org/drm/amd/-/issues/1774 Reviewed-by: Lang Yu <lang.yu@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
