Driver's and ->fill_modes functions are allowed to grab crtc mutexes
(for e.g. load detect). Hence we need to first only grab the general
kms mutex, and only in a second step grab all locks to do the
modesets.
This prevents a deadlock on my gm45 in the tv load detect code called
by drm_helper_probe_single_connector_modes.

Before, it was a function that would set all members of a given struct
containing only int members to -1. Now, it is renamed to
dwc_set_all_params and it works only on the dwc2_core_params struct.
This makes sure that all of the slightly dubious casting and assumptions
happen inside the function instead of by the caller.

Before, this was initialized in pci.c, after the dwc2_hcd_init was
called and the interrupts were enabled. This opened up a small time
window where common interrupts could be triggered, but there was no
handler for them, causing them to keep triggering infinitely and locking
up the machine.
On my RT3052 board this bug could be easily reproduced by hardcoding
the console log level to 8, so that a bunch of debug output from the dwc2
driver was generated inside this time window. This caused the interrupt
lockup to occur almost every time.
By requesting the irq inside dwc2_core_init and by disabling interrupts
before calling dwc2_core_init instead of after, we can be sure the
handler is registered before the interrupts are enabled, which should
close this window.

It seems this flag is intended to pass to irq_set_status_flags, not
request_irq, and is not available on all architectures. Its value
corresponds to IRQF_PROBE_SHARED, which shouldn't be needed for this
driver, so removing this flag should be safe.

Currently this driver calls request_region() in labpc_common_attach()
which is the common attach function for the ISA, PCMCIA, and PCI
versions of the labpc board.
The PCMCIA support is handled in a separate driver, ni_labpc_cs.
That driver sets the dev->iobase after aquiring the resource and
then just passes it to labpc_common_attach() which then sets
dev->iobase again.
The PCI support, currently in this driver, calls mite_setup() to
aquire the resource and then passes it to labpc_common_attach()
to set the dev->iobase.
The ISA support, also in this driver, passes a user supplied
configuration option to labpc_common_attach() which then does
the request_region() before setting the dev->iobase.
Move the request_region() to the ISA support code in labpc_attach()
and set the dev->iobase there before calling the common attach
code.
For the PCI support, also set the dev->iobase before calling the
common code.
This allows removing the extra parameter from labpc_common_attach().
