Currently the IHC (Inter Hart Communication) depends on OpenAMP and rptun. However, the bootloader portion of the IHC doesn't need either of them. Now they are wasting a lot of bootloader space. Reorganize the bootloader portion into a separate file 'mpfs_ihc_sbi.c'. This file contains the OpenSBI vendor extensions, or the only required functionalities for the bootloader. On the other hand, 'mpfs_ihc.c' contains the non-bootloader code. This patch also makes it possible to utilize 2 RPMSG channels. This has been tested so that 2 separate NuttXs on harts 1 and 2 communicate with Linux kernel that runs on harts 3 and 4. New configuration files are added as well: - rpmsg-ch1: sample config for RPMSG - rpmsg-ch2: sample config for another RPMSG channel - rpmsg-sbi: sample bootloader config for RPMSG/OpenSBI Signed-off-by: Eero Nurkkala <eero.nurkkala@offcode.fi>
