This patch adds a support for a new H/W queue type.
This type of queue is for DMA and compute engines jobs, for which
completion notification are sent by H/W.
Command buffer for this queue can be created either through the CB
IOCTL and using the retrieved CB handle, or by preparing a buffer on the
host or device SRAM/DRAM, and using the device address to that buffer.
The patch includes the handling of the 2 options, as well as the
initialization of the H/W queue and its jobs scheduling.

Jobs on some queues must be provided with a handle to a driver command
buffer object, while for other queues, jobs must be provided with an
address to a command buffer.
Currently the distinction is done based on the queue type, which is less
flexible if the same queue type behaves differently on different
types of ASICs.
This patch adds a new queue property for this target, which is
configured per queue type per ASIC type.

A handful of drivers all have a trivial wrapper around their ioctl
handler, but don't call the compat_ptr() conversion function at the
moment. In practice this does not matter, since none of them are used
on the s390 architecture and for all other architectures, compat_ptr()
does not do anything, but using the new compat_ptr_ioctl()
helper makes it more correct in theory, and simplifies the code.
I checked that all ioctl handlers in these files are compatible
and take either pointer arguments or no argument.

The .ioctl and .compat_ioctl file operations have the same prototype so
they can both point to the same function, which works great almost all
the time when all the commands are compatible.
One exception is the s390 architecture, where a compat pointer is only
31 bit wide, and converting it into a 64-bit pointer requires calling
compat_ptr(). Most drivers here will never run in s390, but since we now
have a generic helper for it, it's easy enough to use it consistently.
I double-checked all these drivers to ensure that all ioctl arguments
are used as pointers or are ignored, but are not interpreted as integer
values.

Currently when binding to an spd EEPROM, the at24 drivers logs the
following message:
256 byte spd EEPROM, read-only, 0 bytes/write
The last part is confusing, as by definition you don't write to a
read-only EEPROM, plus "0 bytes/write" makes no sense whatsoever.
I propose to have a different message for read-only EEPROMs, which
does not include this last part.
