Adds OPAL_CONSOLE_WRITE error handling and implements a call to OPAL_CONSOLE_WRITE_BUFFER_SPACE to verify if there's enough space before writing to console. This fixes serial port output getting corrupted on fast writes, like on "dmesg" output. Tested on Raptor Blackbird running powerpc64 BE kernel Reviewed by: luporl Sponsored by: Eldorado Reserach Institute (eldorado.org.br) MFC after: 1 week Differential Revision: https://reviews.freebsd.org/D29063
