ALSA: echoaudio: remove redundant assignment to variable clock

The variable clock is being assigned a value that is never read,
it is being re-assigned a new value in every case in the following
switch statement. The assignment is redundant and can be removed.

Cleans up clang scan build warning:
sound/pci/echoaudio/echoaudio_3g.c:277:2: warning: Value stored
to 'clock' is never read [deadcode.DeadStores]

ALSA: echoaudio: Proper endian notations

Many data fields defined in echoaudio drivers are in little-endian,
hence they should be defined with __le16 or __le32. This makes it
easier to catch the forgotten conversions.

Spotted by sparse, a warning like:
sound/pci/echoaudio/echoaudio_dsp.c:990:36: warning: incorrect type in assignment (different base types)

ALSA: echoaudio: Use standard C definitions of true and false

The echoaudio locally defines TRUE and FALSE. Not only is this
redundant given that C now has a boolean type it results in lots of
warnings as other headers also define these macros, causing duplicate
definitions. Fix this by removing the local defines and converting all
local users to use the standard C true and false instead, simply
removing the macros is less safe due to implicit inclusion of the other
definitons.

[fixed overlooked replacement of FALSE by tiwai]

ALSA: echoaudio: cleanup of unnecessary messages

commit "b5b4a41b392960010fccf1f9ccf8334d612bd450" was dereferencing
chip after it has been freed. This patch fixes that and at the same
time removes some debugging messages, which are unnecessary, as they
are just printing information about entry and exit from a function,
and which switch-case it is executing.
we can easily get from ftrace the information about the entry and exit
from a function.

ALSA: Echoaudio - Add firmware cache #1

Changes the way the firmware is passed through functions.

When CONFIG_PM is enabled the firmware cannot be released because the
driver will need it again to resume the card.
With this patch the firmware is passed as an index of the struct
firmware card_fw[] in place of a pointer. That same index is then used
to locate the firmware in the firmware cache.

[ALSA] echoaudio - increase sleep time at loading firmware

The new ASIC code needs more time to set up.
(Note: the driver still works fine with the old firmware after this change.
The opposite is not true.)
