There are some OMAP1 clock code bits that have no effect:
- crystal_type variable is set to 0 but never changed, then
  crystal_type == 2 condition is never true and ck_ref.rate never set to
  19200000,
- clk->ops->allow_idle() is called from omap_clk_enable_autoidle_all() but
  that op is not configured for any clock, then the function does nothing
  and the op field is not needed,
- ENABLE_ON_INIT flag is set for some clocks but is never checked by any
  code, then not needed.
Drop that code.
