Omar Ramirez Luna eb05f69129 ARM: OMAP: hwmod: partially un-reset hwmods might not be properly enabled
Some IP blocks might not be using/controlling more than one
reset line, this check loosens the restriction to fully use
hwmod framework for those drivers.

E.g.: ipu has reset lines: mmu_cache, cpu0 and cpu1.
- As of now cpu1 is not used and hence (with previous check) the
  IP block isn't fully enabled by hwmod code.
- Usually ipu and dsp processors configure their mmu module first
  and then enable the processors, this involves:
    * Deasserting mmu reset line, and enabling the module.
    * Deasserting cpu0 reset line, and enabling the processor.
  The ones portrayed in this example are controlled through
  rproc_fw_boot in drivers/remoteproc/remoteproc_core.c

While at it, prevent _omap4_module_disable if all the hardreset
lines on an IP block are not under reset.

This will allow the driver to:
  a. Deassert the reset line.
  b. Enable the hwmod through runtime PM default callbacks.
  c. Do its usecase.
  d. Disable hwmod through runtime PM.
  e. Assert the reset line.
