Currently the SCMI driver supports MHUv1, but Arm platforms may have varied versions of MHU driver, with MHUv2 controllers being in the latest Arm platforms. This patch updates the SCMI driver to support MHUv2, specifically that the sender must send the wake-up to the receiver before initiating any data transfer. Also, the existing mhu driver files, css_mhu.c and css_mhu.h, have been moved from the scpi directory to a new directory, css/drivers/mhu.
