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.
