phy: qcom-qmp: Zero-initialize typec switch descriptor

When registering a typec switch, typec_switch_register() expects the
name field of the provided struct typec_switch_desc to be either set to
a valid string or initialized with NULL. If it instead has been
initialized by some random bytes from the stack, we may end up with a
switch name of '(efault)-switch'. Furthermore, if we add multiple
switches, registration may fail due to duplicate sysfs names.

Zero-initialize the switch descriptor to fix this.
