MLK-23675 configs: imx8: change CONFIG_IMX_VSERVICE_SHARED_BUFFER to 0x90400000

Change the buffer to use the real buffer, not vring space.
Because we are going to let M4 publish the resource table into vring
space for kernel usage. uboot will overwrite it, so use the real shared
buffer space 0x90400000

Script:
sed -i "s/CONFIG_IMX_VSERVICE_SHARED_BUFFER=0x90000000/CONFIG_IMX_VSERVICE_SHARED_BUFFER=0x90400000/" configs/*
