common/lcd.c: cleanup use of global variables

console_col, console_row, lcd_line_length, lcd_console_address had
to be declared in board / driver specific code, but were not actually
used there on many boards. Get rid of the global variables.

for completeness, the ack of Bo Shen is for the atmel part
