After commit 0edb555a65 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.
Convert all drivers below sound/soc to use .remove(), with the eventual
goal to drop struct platform_driver::remove_new(). As .remove() and
.remove_new() have the same prototypes, conversion is done by just
changing the structure member name in the driver initializer.

This patch converts the mediatek BT SCO driver code to use the new
unified PCM copy callback. It's a straightforward conversion from
*_user() to *_iter() variants. As copy_form/to_iter() updates the
internal offset at each read/write, we can drop the cur_*_idx counter
in the loop, too.
Note that copy_from/to_iter() returns the copied bytes, hence the
error condition is adjusted accordingly.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

As the mtk_btcvsd_snd_write and mtk_btcvsd_snd_read may return error,
it should be better to catch the exception.

If an error occurs after a successful 'of_iomap()' call, it must be undone
by a corresponding 'iounmap()' call, as already done in the remove
function.
While at it, remove the useless initialization of 'ret' at the beginning of
the function.

We don't need dev_err() messages when platform_get_irq() fails now that
platform_get_irq() prints an error message itself when something goes
wrong. Let's remove these prints with a simple semantic patch.
// <smpl>
@@
expression ret;
struct platform_device *E;
@@
ret =
(
platform_get_irq(E, ...)
|
platform_get_irq_byname(E, ...)

if ( \( ret < 0 \| ret <= 0 \) )
{

-if (ret != -EPROBE_DEFER)
-{ ...
-dev_err(...);
-... }

...
-dev_err(...);
)
...
}
// </smpl>
While we're here, remove braces on if statements that only have one
statement (manually).
