drivers/tty: don't use the byte channel handle as a parameter in ehv_bytechan.c
The ePAPR hypervisor byte channel console driver only supports one byte channel as a console, and the byte channel handle is stored in a global variable. It doesn't make any sense to pass that handle as a parameter to the console functions, since these functions already have access to the global variable.
