OMAP: wait for pwrdm transition after clk_enable()
Enabling clock in a disabled power domain causes the power domain to be
turned on. However, the power transition is not always finished when
clk_enable() returns and this randomly crashes the kernel when an
interrupt happens right after the clk_enable, and the kernel tries to
read the irq status register for that domain.
Why the irq status register is inaccessible, I don't know. Also it
doesn't seem to be related to the module being not powered up, but to
the transition itself.
The same could perhaps happen after clk_disable also, but I have not
witnessed that.
The problem affects at least dss, cam and sgx clocks.
This change waits for the transition to be finished before returning
from omap2_clkdm_clk_enable().

- Stop trying to arrange those dodgey side effects; just leave

- Check that status as part of driver probe, so the PHY can
always be active by the time it's needed. (BUGFIX!)

- Make the irq_chip be the exclusive owner of PWR_EDR (finally).
- Get rid of needless work_struct ... in this irq handling thread,

Stop enabling IRQs on the USB subchip. There's no IRQ handler for
