This patch removes spi speed control codes. We are not using define SPEED to
specify speed of spi, it is not proper way of doing this. It will be
provided by the device tree.

The following functions and variable are removed.
MIN_SPEED, MAX_SPEED, SPEED
wilc_spi_set_max_speed
wilc_spi_max_bus_speed
wilc_spi_default_bus_speed
hif_set_max_bus_speed
hif_set_default_bus_speed

This patch removes spi speed control related functions and variable. We cannot
get exact clock what we need in this way and it can causes some problem in host
side by setting the clock, so remove the codes.
Speed control codes in spi also will removed in next patch, so it's ok to
remove functions in linux_wlan.c and wilc_wlan.c which also not used anymore.

The Following functions and varialbe are removed.
MAX_SPEED, sdio_default_speed
wilc_bus_set_default_speed
wilc_bus_set_max_speed
linux_sdio_set_speed
linux_sdio_get_speed
wilc_sdio_set_max_speed
wilc_sdio_set_default_speed

We want to get rid of all global variables in this driver, and
instead pass device structures from one function to another.
This changes the linux_wlan.c and wilc_wlan.c to do this
for the most part. There are a few exceptions where these
functions are themselves called from another part of the driver
that does not have an instance pointer at hand. Changing those
would be a follow-up step.

There are a few other globals that will have to get moved
into struct wilc at a later point.

So far, my patches tried to do equivalent conversions of the
existing code.  This one goes beyond that by restructuring
how the devices get probed. In particular, the spi driver
no longer creates the netdev until the device is probed,
and I've removed the global wilc_sdio_func and wilc_spi_dev
variables in favor of retrieving them from the wilc_dev
variable that will eventually get passed through all functions
instead of using a global.

The last remaining user of WILC_SDIO macro checks for the correct
time to wait in an interrupt for the PLL to settle. We can
replace this with a runtime check and remove both WILC_SDIO and
WILC_SPI, as we no longer need conditional compilation based on
the hardware type.

As a preparation for turning the SDIO side of wilc1000 into a separate
module, this removes the last direct caller from the core module into
the sdio specific portion. All calls to wilc_sdio_enable_interrupt()
and wilc_sdio_disable_interrupt() now go through a function pointer
in wilc_hif_func. We also change arguments slightly to pass the device,
as we are already touching those lines and the change will be needed
later to remove the global variables.

The wilc_hif_spi and wilc_hif_sdio structures are part of
the bus specific code, and the generic code should have no knowledge
of their addresses.

This changes the code to reference them only from the bus
specific initialization code, which we can then use to split
up the driver into separate modules.

Whether the SDIO function uses an internal or external interrupt
should not be a compiletime decision but be determined at runtime.

This changes the code to pass a GPIO number from the init code
as early as possible, and leaves just one #ifdef WILC_SDIO_IRQ_GPIO
to preserve the previous behavior.

All other locations that check for the interrupt method are turned
into runtime checks based on the gpio number (>=0) or the interrupt
number (>0).

The driver provides an interface for custom power management
and detection that is meant to be filled by people customizing
the driver. The default implementation of this is empty, and
we don't actually want people to have to modify the source code.

If anybody needs this, they need to describe the respective
hardware specifics using device tree or platform data and make
the driver handle this is a more general way.

This removes the empty stubs.

The wilc_wfi_cfgoperations.h header defines the ieee80211_txrx_stypes

There are many global symbols in the wilc1000 driver, some of them
with names like "DEBUG_LEVEL" or "probe" that are not acceptable
for globals in the linux kernel as they may easily conflict with other

wilc or a variation of that to start with wilc_ and to follow
