Add a new hwmod flag to indicate custom reset handling and use it
for devices that require custom reset handling (like dsp, ipu, iva).

Tested PCIe on dra7-evm and dra72-evm.
I need help in testing DSP, IPU, IVA, PRU, GFX, M3 in other platforms.
Or a way to test these cores to see if reset is not broken. Suman?

I won't be able to test this week, and have requested Dave to check on
wkup_m3_rproc driver atleast. I see one potential issue (see my commment
on the other thread), but can confirm that only after testing.

Have you tested multiple probe/removal sequences? Can you check the
return status on the _hardreset_deassert call with your PCIe driver,
believe even that one would return an error on multiple probes.

hmm.. the PCIe driver is built-in and can't be made as module because of other
issues in PCIe core. But looks like the first deassert succeeded since I didn't
observe the boot hang because of PCIe.

Thanks
Kishon

I'll post this series once again after performing these tests.
