ASoC: cs35l34: Fix GPIO name and drop legacy include

This driver includes the legacy GPIO APIs <linux/gpio.h> and
<linux/of_gpio.h> but does not use any symbols from any of
them.

Drop the includes.

Further the driver is requesting "reset-gpios" rather than
just "reset" from the GPIO framework. This is wrong because
the gpiolib core will add "-gpios" before processing the
request from e.g. device tree. Drop the suffix.

The last problem means that the optional RESET GPIO has
never been properly retrieved and used even if it existed,
but nobody noticed.
