Tzung-Bi Shih 3efa0ea743 remoteproc/mediatek: read IPI buffer offset from FW ...

Reads the IPI buffer offset from the FW binary.  The information resides
in addr of .ipi_buffer section.

Moves scp_ipi_init() to rproc_ops::parse_fw() phase.  The IPI buffer can
be initialized only if the offset is clear.

To backward compatible to MT8183 SCP, specify the offset in the board
specific mtk_scp_of_data.  Reads the default offset if the firmware
doesn't have it.
