[PATCH 1/1] usb: typec: tcpm: remove unused static variable 'tcpm_altmode_ops'

[Zhen Lei]

Fixes the following W=1 kernel build warning:

drivers/usb/typec/tcpm/tcpm.c:2107:39: warning: ‘tcpm_altmode_ops’ defined but not used [-Wunused-const-variable=]

The reference to the variable 'tcpm_altmode_ops' is deleted by the
commit a079973f462a ("usb: typec: tcpm: Remove tcpc_config configuration
mechanism").

By the way, the static functions referenced only by the variable
'tcpm_altmode_ops' are deleted accordingly.
