Commit 14485de431b0 ("usb: Use device_get_match_data()") dropped the
unconditional use of ci_hdrc_usb2_of_match resulting in this warning:

drivers/usb/chipidea/ci_hdrc_usb2.c:41:34: warning: unused variable 'ci_hdrc_usb2_of_match' [-Wunused-const-variable]

The fix is to drop of_match_ptr() which is not necessary because DT is
always used for this driver.

Fixes: 14485de431b0 ("usb: Use device_get_match_data()")
Reported-by: kernel test robot <lkp@intel.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202310131627.M43j234A-lkp@intel.com/
