tpm: loongson: Add bufsiz parameter to tpm_loongson_send()

Browse Source 
Commit 5c83b07df9c5 ("tpm: Add a driver for Loongson TPM device") has a
semantic conflict with commit 07d8004d6fb9 ("tpm: add bufsiz parameter
in the .send callback"), as the former change was developed against a
tree without the latter change. This results in a build error:

  drivers/char/tpm/tpm_loongson.c:48:17: error: initialization of 'int (*)(struct tpm_chip *, u8 *, size_t,  size_t)' {aka 'int (*)(struct tpm_chip *, unsigned char *, long unsigned int,  long unsigned int)'} from incompatible pointer type 'int (*)(struct tpm_chip *, u8 *, size_t)' {aka 'int (*)(struct tpm_chip *, unsigned char *, long unsigned int)'} [-Wincompatible-pointer-types]
     48 |         .send = tpm_loongson_send,
        |                 ^~~~~~~~~~~~~~~~~
  drivers/char/tpm/tpm_loongson.c:48:17: note: (near initialization for 'tpm_loongson_ops.send')
  drivers/char/tpm/tpm_loongson.c:31:12: note: 'tpm_loongson_send' declared here
     31 | static int tpm_loongson_send(struct tpm_chip *chip, u8 *buf, size_t count)
        |            ^~~~~~~~~~~~~~~~~

Add the expected bufsiz parameter to tpm_loongson_send() to resolve the
error.
