misc: atsha204a: Don't check for error when waking up the device The device ignores any levels or transitions on the SCL pin when the device is idle, asleep or during waking up. Linux kernel driver for atsha204a (atmel-sha204a.ko) also ignores return value from i2c wakeup send command, see: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/crypto/atmel-i2c.c?h=v5.19#n174 And also userspace Turris libatsha204 library ignores return value from wakeup send command, see: https://gitlab.nic.cz/turris/libatsha204/-/blob/v29.2/src/libatsha204/layer_ni2c.c#L75-76 U-Boot driver should do same thing. Fixes waking up ATSHA204 on Turris 1.x boards.
