[PATCH] OMAP: hwmod: if IDLEST fields are not set, use module defaults

[Kevin Hilman <khilman@deeprootsystems.com>]

In the _setup() hook, check for valid IDLEST fields.  If not set, use
the module defaults since they are the same as the module defaults
for most hwmods.

Problem found because _wait_target_ready() will fail if IDLEST
fields are not valid.

RFC: is this an OK solution, or is the preferred solution to ensure
that all the hwmod data is filled with valid fields.
