Add support for registering SPI slave controllers using the existing SPI
master framework:
- SPI slave controllers must use spi_alloc_slave() instead of
spi_alloc_master(), and should provide an additional callback
"slave_abort" to abort an ongoing SPI transfer request,
- SPI slave controllers are added to a new "spi_slave" device class,
- SPI slave handlers can be bound to the SPI slave device represented
by an SPI slave controller using a DT child node named "slave",
- Alternatively, (un)binding an SPI slave handler to the SPI slave
device represented by an SPI slave controller can be done by
(un)registering the slave device through a sysfs virtual file named
"slave".
From the point of view of an SPI slave protocol handler, an SPI slave
controller looks almost like an ordinary SPI master controller. The only
exception is that a transfer request will block on the remote SPI
master, and may be cancelled using spi_slave_abort().

Max bandwidth vote on each bus device is required to be

SSR framework is specific for MSM kernels. Refactor the callbacks
for SSR framework so that the same powerup/shutdown APIs can be
also used for non-MSM kernels where SSR framework does not exist.

In the case of ffs_free_inst() called, whole ffs_dev structure is
freed. Userspace related API do not check if ffs_dev is freed or
not.
If ffs endpoint is opened by userspace, ffs_free_inst() is executed,
mark inst_exist to false but do not free instance structures until
ffs_data is freed.
Besides, ffs_data is allocated in ffs_fs_mount() while opts->dev
is allocated when ffs instance created. And opts->dev will
be freed when ffs instance freed.
If ffs instance is freed and created once, opts->dev is allocated
to new memory, but since ffs_fs_mount() won't be called in this
case, new opts->dev miss the ffs_data address and
ffs_data->private_data still point to old opts->dev address which
is already freed.
So new allocated opts->dev need to initialize opts->dev->ffs_data,
and ffs_private_data also need to update new allocated opts->dev
address.

If there are continuous data-CRC errors in higher speed modes (SDR104
mode), then driver fallbacks to lower speed mode. But if at all it
fails to fallback to lower speed mode, then that error should be
propagated to the caller so that caller will handle it appropriately.
Without this change, sometime while processing card removal event,
driver fails to detect card removal and treats card as present
eventhough its removed.

Currently same pipe index is used for both QDSS and DPL pipes for SDM660.
This causes QDSS not working in composition 90DB having both QDSS and DPL
interfaces. Hence fix it by changing QDSS pipe index to 3 so that both
QDSS and DPL works fine with 90DB composition on SDM660.
