loongarch/config: Enable TPM TIS customization

LoongArch inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I7QRWR



------------------------------------------

The kernel does not load the TPM device properly
because TPM TIS customization is not enabled,
enabling TPM TIS customization makes the kernel
load the TPM device correctly.
