Looks as though a079973f462a3 ("usb: typec: tcpm: Remove tcpc_config
configuration mechanism") pulled out the only use of 'tcpm_altmode_ops'
last year.  No need to keep it around.

Fixes the following W=1 kernel build warning(s):

 drivers/usb/typec/tcpm/tcpm.c:1551:39: warning: ‘tcpm_altmode_ops’ defined but not used [-Wunused-const-variable=]
 1551 | static const struct typec_altmode_ops tcpm_altmode_ops = {
