media: s5p-mfc: fix mmap support for 64bit arch
commit 05b676ab42f624425d5f6519276e506b812fa058 upstream.
TASK_SIZE is depends on the systems architecture (32 or 64 bits) and it
should not be used for defining offset boundary for mmaping buffers for
CAPTURE and OUTPUT queues. This patch fixes support for MMAP calls on
the CAPTURE queue on 64bit architectures (like ARM64).
