[PATCH v2] drm/amd/display: Guard ACPI calls with CONFIG_ACPI

[sunpeng.li at amd.com]

From: Leo Li <sunpeng.li at amd.com>

To fix CONFIG_ACPI disabled build error.

v2: Instead of ifdef-ing inside function, define a no-op stub for
amdgpu_acpi_get_backlight_caps when CONFIG_ACPI=n

Fixes: ec6f30c776ad ("drm/amd/display: Set default brightness according to ACPI")
