arm: omap: cm_t35: update config file

This patch makes the following updates to the cm_t35 config file:
- Replace "ttyS" in default environment kernel bootargs with the new "ttyO"
  notation.
- Remove "omapfb.debug=y" from default environment kernel bootargs.
- Define a minimal power-on delay for USB hub ports so that slow-to-power-on USB
  sticks will have enough time to become responsive.
- Add support for bootz command
- ulpi_reset is not necessary and always fails with the following error message:
  "ULPI: ulpi_reset: failed writing reset bit"
  So, remove it.
