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.
