The CFGCHIP registers are used by a number of devices, so use a syscon
device to share them. The first consumer of this will be the phy-da8xx-usb
driver.
Add the syscon device and register it.

Currently we have one device created to handle all (maximum 2) eDMAs in the
system.
With this change all eDMA instance will have it's own device/driver.
This change is needed for further cleanups in the eDMA driver stack since
the one device/driver to handle all eDMAs in the system was not flexible
enough and prevents the upcoming work.

For modules having single clock, clk_get should be done with dev_id.
But current davinci implementation handles multiple instances
of the UART devices with single platform_device_register. Hence clk_get
is based on con_id rather than dev_id, this is not correct. Do
platform_device_register for each instance and clk_get on dev_id.

Without this patch, da8xx_register_spi() registers the SPI board info,
the SPI controller, and sets its number of chipselect to the size of the
static spi_board_info array. This is bad because a SPI board info may
declare devices for different SPI buses, and because other code can also
call spi_register_board_info() (e.g. a daughter board might provide
additional SPI devices).
This patch removes the spi_register_board_info() call from
da8xx_register_spi(), renames this last one to da8xx_register_spi_bus()
to be more explicit, takes the number of chipselect as a function
parameter, and updates the impacted board-da8{3,5}0-evm.c, and
board-mityomapl138.c files accordingly. It also sets the SPI platform
data static, as it doesn't need to be exported.

As a first step towards migrating davinci platforms to use common clock
framework, replace all instances of clk_enable() with clk_prepare_enable()
and clk_disable() with clk_disable_unprepare(). Until the platform is
switched to use the CONFIG_HAVE_CLK_PREPARE Kconfig variable, this just
adds a might_sleep() call and would work without any issues.
This will make it easy later to switch to common clk based implementation
of clk driver from DaVinci specific driver.

Davinci McASP header & driver are shared by few OMAP platforms (like

header and Audio specific header helps to share them across platforms.
Audio specific defines is moved to to common

accessed by all related platforms.
While here, correct the header usage (remove multiple header

Davinci platforms may define a default queue for each channel
controller. If one is not defined, the default queue is set to EVENTQ_1.
However, there's no way to distinguish between an unset default queue to
one that is set to EVENTQ_0, as EVENTQ_0 = 0.
Explicitly specify the default queue for all channel controllers on all
Davinci platforms to EVENTQ_1, and don't overwrite it in the EDMA probe
function.
One exception is the DA850 board, for which EVENTQ_1 is not a valid
option for its second channel controller. Use EVENTQ_0 instead for that
channel controller.
