Some drivers set PF_NOFREEZE in their kthread functions which is
completely unnecessary and racy - some part of freezer code doesn't
consider cases where PF_NOFREEZE is set asynchronous to freezer
operations.
In general, there's no reason to allow setting PF_NOFREEZE explicitly.
Remove them and change the documentation to note that setting
PF_NOFREEZE directly isn't allowed.
-v2: Dropped change to twl4030-irq.c as it no longer uses PF_NOFREEZE.

HCI transport drivers may not know what type of radio an AMP device has
so only say whether they're BR/EDR or AMP devices.

When driver is sending a command or data and the firmware is also
sending a sleep event, sometimes it is observed that driver will
continue to send the command/data to firmware right after processing
sleep event. Once sleep event is processed driver is not supposed to
send anything because firmware is in sleep state after that. Previously
interrupt processing was done in SDIO interrupt callback handler.
Now it is done in btmrvl driver main thread to solve the
cross-sending properly.

This is mostly cleanup. There is only one caller and it just checks for
non-zero return values. Still "ret" should be int because we want to return
-EINVAL on errors.

The Marvell Bluetooth driver is full of Enter/Leave debug statements and
all of them are really pointless and only clutter the code. Seems to be
some left-overs when they ported the driver from Windows. For the Linux
driver lets remove these.

After fixing the driver to use skb_put properly for their HCI commands
only a few compiler warnings are left. Add proper casting for them.

The Marvell driver has some weird quirks on how to construct proper SKBs
with Bluetooth HCI commands. Fix it to use skb_put properly and also
use hci_opcode_pack instead of self-crafted macro.

The Marvell core Bluetooth driver has various weird casting and unneeded
braces in its code that makes it hard to read. Remove all of these to
make the code a little bit simpler.
