ASoC: ti: ams-delta: Fix cx81801_receive() argument types

Since types of arguments accepted by tty_ldis_ops::receive_buf() have
changed, the driver no longer builds.

.../linux/sound/soc/ti/ams-delta.c:403:24: error: initialization of 'void (*)(struct tty_struct *, const u8 *, const u8 *, size_t)' {aka 'void (*)(struct tty_struct *, const unsigned char *, const unsigned char *, unsigned int)'} from incompatible pointer type 'void (*)(struct tty_struct *, const u8 *, const char *, int)' {aka 'void (*)(struct tty_struct *, const unsigned char *, const char *, int)'} [-Werror=incompatible-pointer-types]
  403 |         .receive_buf = cx81801_receive,

Fix it.

Fixes: e8161447 ("tty: make tty_ldisc_ops::*buf*() hooks operate on size_t")
Fixes: 892bc209 ("tty: use u8 for flags")
