ide: turn selectproc() method into dev_select() method (take 5)
Turn selectproc() method into dev_select() method by teaching it to write to the device register and moving it from 'struct ide_port_ops' to 'struct ide_tp_ops'. Signed-off-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Cc: benh@kernel.crashing.org Cc: petkovbb@gmail.com [bart: add ->dev_select to at91_ide.c and tx4939.c (__BIG_ENDIAN case)] Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
