[PATCH] ARM: OMAP2+: clockdomain: Fix OMAP4 ISS clk domain to support only SWSUP

[Benoit Cousson]

From: Miguel Vadillo <vadillo at ti.com>

Since CAM domain (ISS) has no module wake-up dependency
with any other clock domain of the device and the dynamic
dependency from L3_main_2 is always disabled, the domain
needs to be in force wakeup in order to be able to access
it for configure (sysconfig) it or use it.

Also since there is no clock in the domain managed automatically
by the hardware, there is no use to configure automatic
clock domain transition. SW should keep the SW_WKUP domain
transition as long as a module in the domain is required to
be functional.

Hi Tony,

Here is a fix that Miguel sent me some time back and that I forgot until
I face the crash again while trying to enable the ISS for test.

Regards,
Benoit
