tty: Update hypervisor tty drivers to use core stdout parsing code.
The evh_bytechan, hvc_opal and hvc_vio drivers all open code the parsing of the stdout node in the device tree. This patch simplifies the driver by removing the duplicated functionality. Signed-off-by: Grant Likely <grant.likely@linaro.org>
