The driver can be compile tested with !CONFIG_OF or !CONFIG_ACPI making
unused.  This fixes compile tests with W=1 by annotating device ID table
as possibly unused:

  drivers/char/tpm/st33zp24/i2c.c:141:34: error: ‘of_st33zp24_i2c_match’ defined but not used [-Werror=unused-const-variable=]
  drivers/char/tpm/st33zp24/spi.c:258:34: error: ‘of_st33zp24_spi_match’ defined but not used [-Werror=unused-const-variable=]
