android: mm: generic: use GRALLOC_HARDWARE_MODULE_ID
PlatformFrameBufferAllocator is an abstraction over gralloc. Right now hardwareModule_ points towards a CAMERA_HARDWARE_MODULE_ID. When gralloc_open() is called we observe: libcamera: DEBUG HAL camera3_hal.cpp:75 Open camera gpu0 libcamera: ERROR Camera camera.cpp:524 Camera in Configured state trying acquire() requiring state Available 01-23 14:14:04.742 370 416 E libcamera: FATAL HAL generic_frame_buffer_allocator.cpp:105 gralloc_open() failed: -87 Which is wrong, gralloc_open() is attempting to re-open the camera HAL, instead of the gralloc HAL. Point to a GRALLOC_HARDWARE_MODULE_ID instead so that we can request buffers from gralloc in android. Note: this adds new dependencies on android's libhardware [1] and on libdl.
