Benoît Cousson 5365efbe29 OMAP: hwmod: Add hardreset management support 
Most processor IPs does have a hardreset signal controlled by the PRM.
This is different of the softreset used for local IP reset from the
SYSCONFIG register.
The granularity can be much finer than orginal HWMOD, for ex, the IVA
hwmod contains 3 reset lines, the IPU 3 as well, the DSP 2...
Since this granularity is needed by the driver, we have to ensure
than one hwmod exist for each hardreset line.

- Store reset lines as hwmod resources that a driver can query by name like
  an irq or sdma line.

- Add two functions for asserting / deasserting reset lines in hwmods
  processor that require manual reset control.
- Add one functions to get the current reset state.
- If an hwmod contains only one line, an automatic assertion / de-assertion
  is done.
  -> de-assert the hardreset line only during enable from disable transition
  -> assert the hardreset line only during shutdown

Note: The hwmods with hardreset line and HWMOD_INIT_NO_RESET flag must be
kept in INITIALIZED state.
They can be properly enabled only if the hardreset line is de-asserted
before.

For information here is the list of IPs with HW reset control
on an OMAP4430 device:

[paul@pwsan.com: made the hardreset functions static; moved the register
 twiddling into prm*.c functions in previous patches; changed the
 function names to conform with hwmod practice]
